Howdy Bhushankumar,

It appears setting the value of 'OrderStatus' to an array of valid values doesn't seem to have an effect to the results, is it be passed to the API correctly?

An example is...

amazonMws.orders.search({
        'Version': '2013-09-01',
        'Action': 'ListOrders',
        'SellerId': 'REMOVED',
        'MWSAuthToken': 'REMOVED',
        'MarketplaceId.Id.1': 'REMOVED',
        'OrderStatus': ["Unshipped", "Pending"],
        'MaxResultsPerPage' : 2, // def: 100, max 100
        'CreatedAfter' : new Date(1, 1, 2018),
        //'LastUpdatedAfter': new Date(13, 12, 2017),

    }, function (error, response) {
        if (error) {
            console.log('error ', error);
            return;
        }
        console.log('response', response);
    });
};

And the orders are returned, but it appears the OrderStatus was completely ignored as the orders that are returned are in multiple statuses, such as "Shipped".

Note: Multiple order statuses can be set, eg Pending and Unshipped as per the docs here http://docs.developer.amazonservices.com/en_IN/orders-2013-09-01/Orders_ListOrders.html

A list of OrderStatus values. Used to select orders with a current status that matches one of the status values that you specify.

Also using the value of :

'OrderStatus': "Unshipped",

Gives this response from Amazon:

error  { Type: 'Sender',
  Code: 'MalformedInput',
  Message: 'Unexpected list element termination',
  RequestId: '34ead115-4407-428b-a5b8-REMOVED' }

Hi i can't run this on node v8.5.0. Can you kindly provide which version that you used?

Great library.
can you please add Subscriptions in type defs.

`

declare class AmazonMWS {

constructor()

constructor(key: string, token: string);

setApiKey(key: string, secret: string): void;

setHost(host?: string, port?: string, protocol?: string): void;

feeds: Feeds;

finances: Finances;

fulfillmentInboundShipment: FulfillmentInboundShipment;

fulfillmentInventory: FulfillmentInventory;

fulfillmentOutboundShipment: FulfillmentOutboundShipment;

merchantFulfillment: MerchantFulfillment;

orders: Orders;

products: Products;

reports: Reports;

sellers: Sellers;

}

`

Every time I make a request, the Headers returned look like this:

{
  "x-mws-quota-max": "unknown",
  "x-mws-quota-remaining": "unknown",
  "x-mws-quota-resetson": "unknown",
  "x-mws-timestamp": "2018-07-12T20:29:43.558Z"
}

As you can see, it doesn't provide any throttling information.

Is there a way to fix this?

Version 0.0.19. This is from a request to "GetMyFeesEstimate." The request was perfectly formed and this tends to happen randomly once in a few hundred operations. For this it is very hard to reproduce on demand.

Apparently MWS did not set a content-type header with the error response. (502 bad gateway)

<?xml version="1.0"?>
<ErrorResponse>
    <Error>
        <Type>Server</Type>
        <Code>500</Code>
        <Message>500 - Server Error</Message>
        <Detail />
    </Error>
</ErrorResponse>

/app/api/node_modules/amazon-mws/lib/AmazonMwsResource.js:211
2018-09-14T22:38:31.732701+00:00 app[worker.1]: if (headers['content-type'].indexOf('charset') > -1 && headers['content-type'].split(';')[0] && headers['content-type'].split(';')[1]) {
TypeError: Cannot read property 'indexOf' of undefined at ClientRequest.<anonymous> (/app/api/node_modules/amazon-mws/lib/AmazonMwsResource.js:211:41)

This wouldn't be a big deal, except for some reason it's bypassing my Promise catch handler and crashing the entire app.

Hi

I have my own account and not a developer account and hence i don't have MWS Auth token, so i leave this field blank but i am getting the following error which using this lib:
error { Type: 'Sender',
Code: 'AccessDenied',
Message: 'Access denied',
RequestId: 'afa979de-7684-4a53-b19d-9a9c5ecd97cd' }

Please suggest how to resolve?

thanks

Hello,

i'm facing an error like Illegal character sequence in iconv while fetching 'GetFeedSubmissionResult'.

Please give suggestions to solve it.

I got GetFeedSubmissionResult to fail, with the error log attached.
log.txt
That's the code I'm using
public async GetFeedSubmissionResult<T>(FeedSubmissionId: string, amcli = this.amcli): Promise<T> { try { const res: T = await amcli.feeds.search(this.BuildRequest({ FeedSubmissionId: FeedSubmissionId }, "GetFeedSubmissionResult")); return res; } catch (e) { throw e; } }
this.BuildRequest(args,action) makes sure all the parameters are setup like that before I call amcli.feeds.search which is amazon-mws:
{ FeedSubmissionId: 'xxxxxxxxxxxx', Version: '2009-01-01', Action: 'GetFeedSubmissionResult', SellerId: 'xxxxxxxxxxxx', MWSAuthToken: 'xxxxxxxxxxxx', 'MarketplaceIdList.Id.1': 'xxxxxxxxxxxx' }

GetLowestPricedOffersForSKU,
GetCompetitivePricingForSKU,
GetLowestOfferListingsForSKU,
GetLowestPricedOffersForSKU,
GetMyPriceForSKU,
GetProductCategoriesForSKU.

All return "XXXXX-XXXX-XX is an invalid SellerSKU for marketplace XXXXXXX".
Have tried all marketplaces and a wide variety of skus that are currently in use and not examples, including skus that my actual products have so I know for a fact some of them are valid. There is a chance this is on amazons end but seems rather unlikely as I have not seen many mentions of this issue.

I am trying to figure out how to get the StatusCode and timestamp from the Headers of an error response. Is this even possible? When logging out the response and error when throttled, there is no StatusCode or Header fields that I can see.

Code:

const params = {
    Version: '2013-09-01',
    Action: 'ListOrders',
    SellerId: process.env.SELLER_ID,
    'MarketplaceId.Id.1': 'ATVPDKIKX0DER',
    MWSAuthToken: process.env.MWS_TOKEN,
    LastUpdatedAfter: '2018-12-14T00:00:00.000Z',
};

amazonMws.orders.search(params, (error, response) => {
    console.log(response);
    console.log(error);
});

Logged in the console:

null
{
  Type: { },
  Code: 'RequestThrottled',
  Message: 'Request is throttled',
  RequestId: 'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx'
}

Hi, I get this error when I try to use orders.search

I have one lambda node.js 8.10 function of importing just this module.
But it gets module initialization error on Lambda.

This issue needs to be fixed ASAP.

Here are some details:

'use strict';

var mws = require('amazon-mws')(process.env.ACCESS_KEY_ID, process.env.SECRET_ACCESS_KEY);

module.exports.handler = async event => {
    console.log(JSON.stringify(event));

    return;
};

Of course, I am setting environment variables correctly and cofirmed.
This simple code will get error on Lambda.

I attached CloudWatch log for this lambda function.

hi @bhushankumarl, thank you very much for this library.
Is it possible to add "Subscription" api ?

I'm trying to request amazon orders with your listOrders example. I want to request orders with the parameter CreatedAfter. After changing this parameter in your function call, the call seems to ignore 'After' and always responses with the 'Before' parameters. It's similar with LastUpdateAfter and Before parameter.

How can we solve this issue?

I am trying to pull data from the GetLowestPricedOffersForSKU products api call, but I appear to be getting XML as JSON attributes in the response. Here the first few lines of the response I am getting:
{"data":[{"<?xml version=\"1.0\"?><GetLowestPricedOffersForSKUResponse xmlns=\"http://mws.amazonservices.com/schema/Products/2011-10-01\">":" <GetLowestPricedOffersForSKUResult MarketplaceID=\"ATVPDKIKX0DER\" SKU=\"20180219_StVincentDePaul@Seneca_16\" ItemCondition=\"Used\" status=\"Success\">"},{"<?xml version=\"1.0\"?><GetLowestPricedOffersForSKUResponse xmlns=\"http://mws.amazonservices.com/schema/Products/2011-10-01\">":" <Identifier>"},{"<?xml version=\"1.0\"?><GetLowestPricedOffersForSKUResponse xmlns=\"http://mws.amazonservices.com/schema/Products/2011-10-01\">":" <MarketplaceId>ATVPDKIKX0DER</MarketplaceId>"},{"<?xml version=\"1.0\"?><GetLowestPricedOffersForSKUResponse xmlns=\"http://mws.amazonservices.com/schema/Products/2011-10-01\">":" <SellerSKU>20180219_StVincentDePaul@Seneca_16</SellerSKU>"},{"<?xml version=\"1.0\"?><GetLowestPricedOffersForSKUResponse xmlns=\"http://mws.amazonservices.com/schema/Products/2011-10-01\">":" <ItemCondition>Used</ItemCondition>"},{"<?xml version=\"1.0\"?><GetLowestPricedOffersForSKUResponse xmlns=\"http://mws.amazonservices.com/schema/Products/2011-10-01\">":" <TimeOfOfferChange>2018-07-13T22:18:20.937Z</TimeOfOfferChange>"},{"<?xml version=\"1.0\"?><GetLowestPricedOffersForSKUResponse xmlns=\"http://mws.amazonservices.com/schema/Products/2011-10-01\">":" </Identifier>"}...

What is the best way to handle status codes / errors?

I don't see anything in the docs about errors. I'm most interested in 500 status codes coming from MWS servers so I know I can retry. The problem is I cannot replicate a 500 status code from MWS. I'm also not sure how you're handling 500 status codes. The only place I've been able to find the status codes MWS returns is when a successful "response" is sent back in the "lastResponse.statusCode. When an "error" is sent back it's missing the status code. The only thing available for the "error" is the "code" which can be different depending on the API your calling. Does the "code" sent back in the "error" always correspond to the api doc error handling? Is there a better way for me to search for status codes rather than code messages? Does a 500 status code return an "error" or a "response"? Thanks so much for your help!

This is an example from GetMyPriceForASIN, but I believe the same change applies to all product info operations. A couple fields were removed from the results.

[
  {
    "ASIN": "B01BICBEQ2", // <-- NO LONGER PRESENT
    "status": "Success",  // <-- NO LONGER PRESENT
    "Product": {
      "Identifiers": {
        "MarketplaceASIN": {
          "MarketplaceId": "A1F83G8C2ARO7P",
          "ASIN": "B01BICBEQ2"
        }
      },
      "Offers": {}
    }
  }
]

I've already fixed on my end. Just for your info or others who may have problems after upgrade. Any breaking changes should be noted with a semver major version release.

I noticed that some characters gets corrupted when I use GetReport, these characters should be non-ascii characters like apostrophes and the degree one, indeed when I download the flat file from Seller Central characters are right.
Using hex editor I noticed that these characters are always EF BF BD when using amazon-mws, but they should represent a variety of characters.

This is an example of a GetReport of GET_FLAT_FILE_ORDERS_DATA

In this screenshot ship-address-1 should be 'Via del Gesù', other characters are corrupted in this report.
Thanks for your time, this issue apart, this library is awesome.

Need to change host name to mws.amazonservices.in. allow to pass host name.

Hello,
I have observed we do not get the headers in the response of Amazon using this API. This means i cannt handle throttling since the info is not passed, and i think the library itself dont handle it.

Please tell me how to get the headers or how to handle it.

thanks

I am constructing my request for ListOrders with the following parameters:

// mws params used by all listorders requests
    const mwsParams = {
        Version: '2013-09-01',
        SellerId: sellerId,
        'MarketplaceId.Id.1': 'ATVPDKIKX0DER',
    };

    // send ListOrders request
    const listOrdersRequest = () => amazonMws.orders.search({
        ...mwsParams,
        Action: 'ListOrders',
        MWSAuthToken: mwsToken,
        LastUpdatedAfter: lastUpdatedAfter,
    });

I will sometimes get the following response:

{ 
     Type: 'Sender',
     Code: 'InvalidParameterValue',
     Message:  'The LastUpdatedAfter date is after the LastUpdatedBefore date.',
     RequestId:  '4afa4c76-dcca-4f00-b720-feaa3b37e067' 
} 

This leads me to believe that the client is creating the LastUpdatedBefore parameter without my passing the parameter to orders.search. If anyone can shed some light on how to prevent the parameter from getting added to my request or offer some helpful insight as to what is going on here, I would truly be thankful. I'm really stumped how to proceed.

My intent is to send a request to the endpoint to get orders updated since the timestamp taken from the last time I sent the request

Thank you for this library. It's really useful.

i am getting "the Content-MD5 HTTP header you passed for your feed did not match the Content-MD5 we calculated for your feed" when try to SubmitFeed.

My codes are here;

 const data = 'sku	product-id	product-id-type	price	minimum-seller-allowed-price	maximum-seller-allowed-price	item-condition	add-delete	fulfillment-center-id	batteries_required	supplier_declared_dg_hz_regulation1

    } catch (error) {

      console.log("ERROR:", error);
    }

i used FeedSubmit successfully on scratchpad.
i checked AmazonMwsResource.js file. The ContentMD5 as same as scratchpad.

i don't understand where is the wrong? But i am getting this error...

Could you help me, please ?

How do I properly override line 4 of amazon-mws.js

AmazonMws.DEFAULT_HOST = 'mws-eu.amazonservices.com';

Other Regions, namely EU (Germany, UK, etc.) need to connect to that host to get their data, otherwise, with the same Secret and MWS Token, we only get a 401 access denied

For this functionality I did apply these changes.
requestreport.txt

Good afternoon.

There's any way to get the items by category report? I have alredy enabled this feature in my seller account contacting with amazon, and i can get this report from sellercentral, but i don't know how to request it from this tool (How to pass the category parameter, because if you don't provide one cat, you will break the amazon function). I don't found nothing about it in forums or documentation, only the query

I would be very grateful if someone could help me.

Thanks a lot for your time and this amazing tool.

hi there,

I'm lopping a search report (Report Request List) (to get the generated id when ready) in a setInterval but one the second run (and beyond) I get a message:

'The request signature we calculated does not match the signature you provided. Check your AWS Secret Access Key and signing method. Consult the service documentation for details.'

Code:

const paramCheckReportStatus = {
        Version: '2009-01-01',
        Action: 'GetReportRequestList',
        SellerId: sellerID,
        MWSAuthToken: 'MWS_AUTH_TOKEN',
        'ReportRequestIdList.Id.1': ReportRequestId,
    };

 setInterval(() => {
        amazonMws.reports.search(paramCheckReportStatus, (error, response) => {
            if (error) {
                console.log('error ', error);
            }
            console.log('response', response);
        });
    }, 5000);

What am I missing here?

Thanks

PS: I verified the ReportRequestId and it's correct (I'm first running the submit report and getting the response)

Keys named "Value" have been replaced with "_" in all output. Example from GetCompetitivePricingForASIN

Before:

 "NumberOfOfferListings": {
          "OfferListingCount": [
            {
              "condition": "New",
              "Value": "21"
            },
            {
              "condition": "Any",
              "Value": "21"
            }
          ]
        }
      }

After:

"NumberOfOfferListings": {
          "OfferListingCount": [
            {
              "_": "21",
              "condition": "New"
            },
            {
              "_": "11",
              "condition": "Used"
            },
            {
              "_": "32",
              "condition": "Any"
            }
          ]
        }
      }

After fixing this, you should record raw XML output from specific MWS API calls and run that through your tests to ensure the JSON output never changes between builds.

I see, you are using xml2json but the JSON output isn't most appealing and easy to use.

For eg:
I get the response like below
[ { '<ListInventorySupplyResponse xmlns="http://mws.amazonaws.com/FulfillmentInventory/2010-10-01/">': ' <ListInventorySupplyResult>' }, { '<ListInventorySupplyResponse xmlns="http://mws.amazonaws.com/FulfillmentInventory/2010-10-01/">': ' <MarketplaceId>MarketplaceId</MarketplaceId>' }, { '<ListInventorySupplyResponse xmlns="http://mws.amazonaws.com/FulfillmentInventory/2010-10-01/">': ' <InventorySupplyList>' }, { '<ListInventorySupplyResponse xmlns="http://mws.amazonaws.com/FulfillmentInventory/2010-10-01/">': ' <member>' }, { '<ListInventorySupplyResponse xmlns="http://mws.amazonaws.com/FulfillmentInventory/2010-10-01/">': ' <Condition>NewItem</Condition>' }, { '<ListInventorySupplyResponse xmlns="http://mws.amazonaws.com/FulfillmentInventory/2010-10-01/">': ' <SupplyDetail/>' }, { '<ListInventorySupplyResponse xmlns="http://mws.amazonaws.com/FulfillmentInventory/2010-10-01/">': ' <TotalSupplyQuantity>1447</TotalSupplyQuantity>' }, { '<ListInventorySupplyResponse xmlns="http://mws.amazonaws.com/FulfillmentInventory/2010-10-01/">': ' <EarliestAvailability>' }, { '<ListInventorySupplyResponse xmlns="http://mws.amazonaws.com/FulfillmentInventory/2010-10-01/">': ' <TimepointType>Immediately</TimepointType>' }, { '<ListInventorySupplyResponse xmlns="http://mws.amazonaws.com/FulfillmentInventory/2010-10-01/">': ' </EarliestAvailability>' }, { '<ListInventorySupplyResponse xmlns="http://mws.amazonaws.com/FulfillmentInventory/2010-10-01/">': ' <FNSKU>FNSKU</FNSKU>' }, { '<ListInventorySupplyResponse xmlns="http://mws.amazonaws.com/FulfillmentInventory/2010-10-01/">': ' <InStockSupplyQuantity>147</InStockSupplyQuantity>' }, { '<ListInventorySupplyResponse xmlns="http://mws.amazonaws.com/FulfillmentInventory/2010-10-01/">': ' <ASIN>ASIN</ASIN>' }, { '<ListInventorySupplyResponse xmlns="http://mws.amazonaws.com/FulfillmentInventory/2010-10-01/">': ' <SellerSKU>SellerSKU</SellerSKU>' }, { '<ListInventorySupplyResponse xmlns="http://mws.amazonaws.com/FulfillmentInventory/2010-10-01/">': ' </member>' }, { '<ListInventorySupplyResponse xmlns="http://mws.amazonaws.com/FulfillmentInventory/2010-10-01/">': ' </InventorySupplyList>' }, { '<ListInventorySupplyResponse xmlns="http://mws.amazonaws.com/FulfillmentInventory/2010-10-01/">': ' </ListInventorySupplyResult>' }, { '<ListInventorySupplyResponse xmlns="http://mws.amazonaws.com/FulfillmentInventory/2010-10-01/">': ' <ResponseMetadata>' }, { '<ListInventorySupplyResponse xmlns="http://mws.amazonaws.com/FulfillmentInventory/2010-10-01/">': ' <RequestId>5ome-24ndom-id</RequestId>' }, { '<ListInventorySupplyResponse xmlns="http://mws.amazonaws.com/FulfillmentInventory/2010-10-01/">': ' </ResponseMetadata>' }, { '<ListInventorySupplyResponse xmlns="http://mws.amazonaws.com/FulfillmentInventory/2010-10-01/">': '</ListInventorySupplyResponse>' } ]

While expected format is:

{"ListInventorySupplyResponse":{"xmlns":"http://mws.amazonaws.com/FulfillmentInventory/2010-10-01/","ListInventorySupplyResult":{"MarketplaceId":"MarketplaceId","InventorySupplyList":{"member":{"Condition":"NewItem","SupplyDetail":{},"TotalSupplyQuantity":"1447","EarliestAvailability":{"TimepointType":"Immediately"},"FNSKU":"FNSKU","InStockSupplyQuantity":"1447","ASIN":"ASIN","SellerSKU":"SellerSKU"}}},"ResponseMetadata":{"RequestId":"5ome-24ndom-id"}}}'
`

Is this fine and expected result?

Thanks

How to access all the API's through MWS_AUTH_TOKEN without providing access_key and secret_key, as I have studied in amazon document that with out key's you can access the api's with the help of MWS_AUTH_TOKEN

Can you help me out with small example, as i have never seen in you existing code with such functionality as you have already saved the access_key and secret_key. I don't want to use the both

let accessSecret = process.env.AWS_SECRET_ACCESS_KEY;

const amazonMws = require("amazon-mws")(accessKey, accessSecret);

let feesLookUp = async (req, res) => {
  const { ASIN, inputPrice } = req.body;
  //   console.log("res", ASIN, inputPrice);

  await amazonMws.products.searchFor(

I have tried alot of different possibilities with strings and no strings but no luck. This is my error which is internal here and my scratchpad works. I also got ListMatchingProducts to work so i know my keys are fine. Also the console log is null but my req.body is consoled log from postman just fine.

x-mws-quota-resetsOn: Wed, 06 Mar 2013 19:07:58 GMT

Is it possible to expose these somehow?

Thanks.

Hi,

I am trying to use below mws api using this module. But getting Access Denied error. But things are working fine if I use the same api with same parameters using scratchpad.

var amazonMws = require('amazon-mws')('AWS_ACCESS_KEY_ID','Sec_key');

amazonMws.products.searchFor({
'Version': '2011-10-01',
'Action': 'GetLowestPricedOffersForSKU',
'SellerId': 'SellerID',
'MWSAuthToken': 'authtoken',
'MarketplaceId': 'A21TJRUUN4KGV',
'SellerSKU': 'skuid',
'ItemCondition': 'New'
}, function (error, response) {
if (error) {
console.log('error ', error);
return;
}
console.log('response ', response);
});

Response:

Line 363 here I can see we have:

var host = self.overrideHost || self._AmazonMws.getApiField('host');

But how on earth do I override/set the host value before making the request?

Generally a license has terms and conditions.

Can you clarify on the LICENSE part? Who can use it and how?

Thanks

Thank you for developing this module. I looked up bunch of modules out there and this is by far the best I tried so far. It helped my workflow a lot. Thank you.

I however had some issues with specific apis and was wondering if you can help me. Thanks in adance.

Hi,

I'm always getting access denied although the credentials are correct since I've tested the same credentials with https://github.com/beardon/mws-api and the MWS Scratchpad

My Code:

const { MWS } = require("../config/dev.js");

const account = "XXXXXX"
const amazonMws = new MwsApi();

amazonMws.setApiKey(
  process.env.AWS_ACCESS_KEY_ID,
  process.env.AWS_SECRET_ACCESS_KEY
);


amazonMws.orders.search(
  {
    Version: "2013-09-01",
    Action: "ListOrders",
    SellerId: MWS.merchantId[account], //"SELLER_ID",
    MWSAuthToken: MWS.authToken, //"MWS_AUTH_TOKEN",
    "MarketplaceId.Id.1": MWS.MarketplaceId.de, //"MARKET_PLEACE_ID_1",

  function(error, response) {
    if (error) {
      console.log("error ", error);
      return;
    }
    console.log("response", response);
  }
);

Hi,
I am using the Orders methods. But I couldn't find the ListOrdersByNextToken in any document. Has this function been supported yet? If not, do you have any workaround for it?

Many thanks!

Hello,

I can not retrieve a report of all products from a sellercentral account with this method:

    var ReportRequestId = '10101010XXX';
    amazonMws.reports.search({
        'Version': '2009-01-01',
        'Action': 'GetReportRequestList',
        'SellerId': 'SELLER_ID',
        'MWSAuthToken': 'MWS_AUTH_TOKEN',
        'ReportRequestIdList.Id.1': ReportRequestId
    }, function (error, response) {
        if (error) {
            console.log('error ', error);
            return;
        }
        console.log('response', response);
    });  

It returns to me this:

"HasNext": "false",
         "ReportRequestInfo": {
             "ReportType": "_GET_MERCHANT_LISTINGS_ALL_DATA_",
                 "ReportProcessingStatus": "_SUBMITTED_",
                 "EndDate": "2019-03-26T09:16:33+00:00",
                 "Scheduled": "false",
                 "ReportRequestId": "64163017981",
                 "SubmittedDate": "2019-03-26T09:16:33+00:00",
                 "StartDate": "2019-03-26T09:16:33+00:00"
             },
     "ResponseMetadata": {
             "RequestId": "d2cab60e-30a5-47d1-8555-248c313bb0a6"
             },
     "Headers": {...},
"StatusCode": 200
}

I do not have the ReportId in the request response

That should have returned to me this:

<GetReportListResponse xmlns="http://mws.amazonaws.com/doc/2009-01-01/">
  <GetReportListResult>
    <HasNext>false</HasNext>
    <ReportInfo>

      <Acknowledged>false</Acknowledged>
      <ReportId>15521486795017981</ReportId>
      <ReportRequestId>64163017981</ReportRequestId>

  <ResponseMetadata>
    <RequestId>03e99980-121c-4df9-a69c-58eb4c606094</RequestId>
  </ResponseMetadata>
</GetReportListResponse>

I am uploading a product to FR using a SubmitFeed with FlatFile,it works.Great!
But,I found some garbled text, like " santé". Actually,it is "santé".
This is my code:

It may be the reason for content-type,i want to setup content-type="text/tab-separated-values; charset=iso-8859-1" try fix it.

Reports API, action: "GetReport", type: "GET_V2_SETTLEMENT_REPORT_DATA_XML" report does not parse the XML data to JSON. The issue is presenting itself in the "AmazonMwsResource.js" file inside function "processResponseType" on line 172 of version 0.0.19. It's seeing the content-type as "plain/text" although amazon is responding with XML data. The res.headers['content-type'] is showing as "plain/text". This is what's causing the problem because it causes the if statement on line 172 to fail which means the xml2js parser never runs. The "else" statement runs instead which tries to parse XML data using a CSV parser. If the same request is run through MWS scratchpad amazon responds with a res.headers['content-type'] of "text/xml" which is correct and would allow the XML2JS parser to run. Now sure if for some reason amazon is responding with the wrong content-type or if the content-type is accidentally being changed somewhere.

Dear Bhushankumar,

I tried this example below with some codes changed,

https://github.com/bhushankumarl/amazon-mws/blob/master/examples/javaScript/fulfillmentInventory/listInventorySupply.js

We have 160+ ASINs in our store, but I was only able to fetch 100 of them before getting an error.

below is the code, please can you help check?

//----------------------code starts-----------------------------

var auth = require("./auth");
var amazonMws = require('amazon-mws')(auth.accessKey,auth.secretKey);

var query = {
'Version': '2010-10-01',
'Action': 'ListInventorySupply',
'SellerId': auth.sellerID,
'MWSAuthToken': auth.token,
'MarketplaceId': auth.marketplaceID,
'QueryStartDateTime': new Date(01, 04, 2018)
}

var nextQuery = {

'SellerId': auth.sellerID,
'MarketplaceId': auth.marketplaceID,
'Version': '2010-10-01',
"AWSAccessKeyId": auth.token,
'MWSAuthToken': auth.token,
'Path': "/FulfillmentInventory/2010-10-01"

}

function listInventory(query){

amazonMws.fulfillmentInventory.search(query, function (error, response) {
    if (error) {

    	console.log(nextQuery);

        console.log('error ', error);
        return;
    }else{

    	// console.log(response);

    	var members = response.InventorySupplyList.member;

    	console.log("------------------------------");
    	console.log(members.length);
    	console.log("------------------------------");

    	for (var i = members.length - 1; i >= 0; i--) {
    		console.log(members[i]);
    	}

    	try{

			var nextToken = response.NextToken;

			console.log("------------------------------");

			console.log(nextToken);

			console.log("------------------------------");


			nextQuery["NextToken"] = nextToken;
			nextQuery["Action"] = "ListInventorySupplyByNextToken";


			listInventory(nextQuery);


		}catch(e){


			console.log("All Fetched.");
		}

    }
    
});

}

listInventory(query);

//----------------------code ends-----------------------------

and here is the error msg I get:

error { Type: 'Sender',
Code: 'SignatureDoesNotMatch',
Message: 'The request signature we calculated does not match the signature you provided. Check your AWS Secret Access Key and signing method. Consult the service documentation for details.',

I appreciate your kind attention to this issue. Thank you so very much!

Occasionally MWS is spitting back this in response to an otherwise correct request:

<?xml version="1.0"?>
<ErrorResponse>
    <Error>
        <Type>Server</Type>
        <Code>500</Code>
        <Message>500 - Server Error</Message>
        <Detail />
    </Error>
</ErrorResponse>

In that case this library crashes with this error message, instead of returning proper error JSON:

There should be a proper catch added to handle MWS server errors.

Only the Reports API is included. Any plan to enrich it? Thank you

Greetings. I've noticed that when i request and get the items from a report listing (for example, merchant report), some sku's have accents in it, but not decoded. Example:

"Champú anticaspa" --> "Champ� anticaspa".

In seller central it's displayed properly. This it's happening with product-names too when i get merchant report items.

I've tried decoding the XML in my javascript, but without results.

Thanks so much.

Not sure if a bug, or expected behaviour. But the headers for throttling always return unknown for the GetOrder command.

  Headers:
   { 'x-mws-quota-max': 'unknown',
     'x-mws-quota-remaining': 'unknown',
     'x-mws-quota-resetson': 'unknown',
     'x-mws-timestamp': '2018-06-06T17:57:30.568Z' } }

The library works fine for some, including, ListOrders, but when I try to get the product information. I get the following error. I used the example code provided.

This is a result for a _POST_FLAT_FILE_PRICEANDQUANTITYONLY_UPDATE_DATA_ feed. I submitted the command exactly per the example in the README.

It is probably best if you just return the text response without trying to parse it.

First of all, thanks for this useful piece of software.

async function getFeedResult(amazonAcc, feedId) {
try {
var request = {
'Version': '2009-01-01',
'Action': 'GetFeedSubmissionResult',
'SellerId': amazonAcc.sellerId,
'MWSAuthToken': amazonAcc.MWSAuthToken,
'FeedSubmissionId': feedId
}
var res = await amazonMws.feeds.search(request);
return res;
}
catch (err) {
console.log("Error AmazonUpload.getFeedResult");
throw (err);
}
}
I'm trying to get a FeedSubmissionResult as per the documentation but I get this error:

node_modules/amazon-mws/lib/AmazonMwsResource.js:269
response.Headers = ResponseHeaders;
^

TypeError: Cannot set property 'Headers' of undefined

The credentials are okay, other feed calls are working okay, the call was successful from the amazon scratchpad https://mws.amazonservices.com/scratchpad/index.html .

Seems response is undefined but not sure why. Thanks
