I'm trying to run the poc on my local machine, followed the doc for the client and the api,
As I try to upload a file I get this error:
"Access to XMLHttpRequest at 'http://localhost:4000/ipfs' from origin 'http://localhost:3000' has been blocked by CORS policy:"

Now I'm aware about cross domain ajax requests and understand the underlying security issue.
But right now both scripts are running locally, so they should be able to communicate...or I'm missing something?

my config files for api and client are the following:

{ "node": { "provider": "https://nodes.thetangle.org:443", "depth": 3, "mwm": 9 }, "ipfs": { "provider": "cloudflare-ipfs.com", "token": "MYIPFSNODE_TOKEN" }, "dynamoDbConnection": { "region": "AWS-REGION", "accessKeyId": "AWS-ACCESS-KEY-ID", "secretAccessKey": "AWS-SECRET-ACCESS-KEY", "dbTablePrefix": "DATABASE-TABLE-PREFIX" }, "allowedDomains": [ "https://ipfs.iota.works", "https://ipfs.iota.org", "cloudflare-ipfs.com" ] }

{ "apiEndpoint": "http://localhost:4000/", "ipfsGateway": "https://ipfs.io/ipfs/:hash", "tangleExplorer": { "transactions": "https://utils.iota.org/transaction/:transactionHash", "bundles": "https://utils.iota.org/bundle/:bundleHash" }, "googleAnalyticsId": "" }

under ./api, executed 'npm run build' without error.
However, runing 'now' for deployment, there is an error message saying
'Error: No output directory named "public" found.'
A more detailed information can be found at https://zeit.co/johnpeng968/iota-poc-ipfs-api/6c11s3ph6.
But I found the 'public' directory was there under my project root ~project/my-iota-app/.
The package.json under project root is
{
"name": "my-iota-app",
"version": "0.1.0",
"private": true,

}
}

I am trying to setup a local test environment (both client and api) by running client/api by npm start.

Getting back errors as following:

client (localhost:3000):
There was a problem communicating with the API.
Error: Request failed with status code 404

api (localhost:4000):

[email protected] start /root/project/my-iota-app/src/api > node ./dist/index Started API Server on port 4000 v1.2.1 Running Config 'local' ===> GET / {} <=== duration: 11ms { name: 'iota-poc-ipfs-api', version: '1.2.1' } ===> GET / {} <=== duration: 1ms { name: 'iota-poc-ipfs-api', version: '1.2.1' }

Hi,

When I executed 'npm run dev-start', it complained: Cannot find module '../data/config.local.json'.

I found that there is a config.template.json under ./api/src/data. Are they related?

How to fix this problem?

Thank you in advance.

Online demo at https://ipfs.iota.org/ giving a "TypeError: Cannot read property 'hash' of undefined
" error when trying to upload a file

I'm trying to run the poc on my local machine, followed the doc for the client and the api,
As I try to upload a file I get this error:
{"success":false,"message":"ResourceNotFoundException: Requested resource not found"}

I started ipfs server on DigitalOcean and run DynamoDB on aws and provided workable credentials(both for dynamoDbConnection and for ipfs) in config files

Problem that when I try to put file into storage I got above error message.
It is not so easy to debug error.

May be you could assume where is the problem?

I encountered a problem when compiling, the error message is as following:
(npm install @types/ipfs-http-client doesn't help...)

/root/project/my-iota-app/src/api/src/routes/ipfsStore.ts
TypeScript error in /root/project/my-iota-app/src/api/src/routes/ipfsStore.ts(4,24):
Could not find a declaration file for module 'ipfs-http-client'. '/root/project/my-iota-app/src/api/node_modules/ipfs-http-client/src/index.js' implicitly has an 'any' type.
Try npm install @types/ipfs-http-client if it exists or add a new declaration (.d.ts) file containing declare module 'ipfs-http-client'; TS7016

2 | import { asTransactionTrytes } from "@iota/transaction-converter";
3 | import crypto from "crypto";

4 | import ipfsClient from "ipfs-http-client";

6 | import { IIPFSStoreRequest } from "../models/api/IIPFSStoreRequest";
7 | import { IIPFSStoreResponse } from "../models/api/IIPFSStoreResponse";

when ever I upload a file it gives me this error and I don't know from which file its giving this error.

"TypeError: Cannot set property 'seed' of undefined"

please help...
