The channel join procedure fails sometimes when createTradeApp.js is run, possibly because of a race condition.

This is a placeholder. Need to note down the symptoms and repro method

Hello, it's me again. I followed your book and it was very clear in all the steps and more useful than the docs in getting started with fabric

I got an error a few days back, an error while passing nodejs commands to the blockchain (can't recollect which one but i guess it is channel/create or channel/join)

After many days of hunting around, solved it from the below link.

@GowriR Thanks, changing the channel name fix the issue... very strange !

@antitoine Try creating the genesis.block and chaneel.tx with different channel names - i had a similar error a few days back
antitoine August 2, 2018 12:22 PM
Anyone can help me on this error ? Orderer Server Status Code: (400**) BAD_REQUEST**. Description: error authorizing update: error validating ReadSet: existing config does not contain element for [Group] /Channel/Application/Org1MSP but was in the read set

https://stackoverflow.com/questions/51590202/channel-creation-fails-in-hyperledger-fabric-v1-2

Could you help me understand why this happens and why creating the genesis.block with a different channel ID (in the book - no channel ID was specified), from the channel.tx creation, solves the issue?

Thanks

I am having trouble with the "brew install gnu-tar --with-default-names command". When I run it, I get the error "Error: invalid option: --with-default-names". Subsequently, when I attempt to run the "make docker" command to build images for various network components, I get the following error:

In the organization structure of the initial version of the network, a single organization encompasses banker and client for the importing as well as the exporting side (thereby conflating the role of Importer and ImporterBank, and Exporter and ExporterBank, respectively.)

Currently, the access control mechanisms that have been built cannot distinguish these two roles, neither in chaincode nor in the application.

There are two ways to fix this. We probably should implement both:

1. Have the organization MSP issue certificates with different attributes to banker and client. Then change chaincode logic to check for the right attributes before executing the transaction.
2. Have the web service (in application) associate different user IDs with different roles, and control access to chaincode functions at that level. We could also consider adding a role parameter to the chaincode arguments list (we would have to augment the chaincode too.)

Anyone want to take a shot at this? I don't think this is very urgent, as we can discuss access control theoretically in the book and even leave the implementation as a reader exercise. In an case, the code can have a (parallel) life of its own, independent of the book. We'll just need to make clear what version of the code the book is referring to.

Hello Experts,

I am referring to the book "Hands-On Blockchain with Hyperledger" (By Nitin Gaur, Salman Baset etc) to create a sample trade finance logistic network as given in the ebook.

I am able to run the below commands and start the network

./trade.sh up

docker ps -a will list below containers

But when I run it in Dev network I am not getting any list of containers.

$ ./trade.sh up -d true

docker ps -a will return an empty list

Even I also run clean command (./trade.sh clean -d true) but still, no container created. Please let me know where is the issue.

in page 106, I do $ peer chaincode invoke -n tw -c '{"Args":["requestTrade","50000","Wood for Toys"]}' -C tradechannel.
I get the following error: Incorrect number of arguments. Expecting 3: {ID, Amount, Description of Goods}. Found 2)

It seems logical to me as the in the go code of func requestTrade() (in tradeWorkflow.go), the args is only 2 elements long as the name of the function is not included.
But then also, I do not understand what you expect in line 206 in args[0] when you do tradeKey, err = getTradeKey(stub, args[0])

I use trade-finance-logistics master, fabric 1.1, trade_workflow_v1.

Thank you for your support.

Hi,

I run below script to package smart contract:

docker exec -e CHANNEL_NAME=tradechannel -e CC_LANGUAGE=node -e CC_LABEL=trade -e CC_VERSION=v1 trade_cli cli_scripts/chaincode.sh package

There is error as:

OCI runtime exec failed: exec failed: container_linux.go:380: starting container process caused: exec: "cli_scripts/chaincode.sh": stat cli_scripts/chaincode.sh: no such file or directory: unknown

Any idea how to fix this?

Thx in advance,

Currently the middleware scripts and application web server are configured to run on the host machine. For a cleaner launch, and for consistency with the network setup, we ought to run them in isolated containers too.

Unable to generate crypto config and genesis block. Getting some error.

I'm trying to set up the network part.
I ran docker-compose -f docker-compose-e2e-template.yaml up but I receive the following errors:

ca_peerImporterOrg | Error: File specified by 'tls.keyfile' do
t exist: /etc/hyperledger/fabric-ca-server-config/IMPORTER_CA_PRIVATE_KEY
ca_peerExporterOrg | Error: File specified by 'tls.keyfile' do

ca_peerRegulatorOrg | Error: File specified by 'tls.keyfile' do
t exist: /etc/hyperledger/fabric-ca-server-config/REGULATOR_CA_PRIVATE_KEY

Did anyone have the same issue? How to solve this?
I just need to get the app running without any modification.

Thanks in advance!

I have completed the network part followed by the middleware part. Then I am trying to run the application by running "node app.js", however I am getting the following error.

$node app.js

  Failed to generate orderer genesis block...

ISSUE: When running ./trade.sh generate -c tradechannel command for testing, I found sed command has issue on osx.

SOLVE: change [sed -i] with [sed -i ""].

REASON: Unlike Ubuntu, OS X requires the extension to be explicitly specified. The workaround is to set an empty string:
$ sed -i '' 's/megatron/pony/g' /path/to/file.txt

Hi - I am attempting to run middleware/createTradeApp.js with release-1.4, but am getting an error (please see below)

I am following the instructions in the README.md at https://github.com/HyperledgerHandsOn/trade-finance-logistics/tree/release-1.4/middleware. I believe that all of my config parameters in the network and middleware directories are consistent.

I believe that my error is not related to Issue #3 (Race condition during channel join in createTradeApp.js). (As one attempt to debug, I extended the sleep time at line 196 of create-channel.js, but still getting same error.)

Here is the console output when I invoke createTradeApp.js:

Can we get any solution to above error.

Thank you.

When i run configtxgen to generate genesis block i encountered the following errors

And after digging deeper, i thought it was caused by the wrong yaml definition, we used alias ChannelCapabilities before anchor ChannelCapabilities, so the parser thought it was invalid, and the following are the yaml specification about Anchor and Alias

3.3.1. Well-Formed Streams and Identified Aliases
A well-formed character stream must match the BNF productions specified in the following chapters. Successful loading also requires that each alias shall refer to a previous node identified by the anchor. A YAML processor should reject ill-formed streams and unidentified aliases. A YAML processor may recover from syntax errors, possibly by ignoring certain parts of the input, but it must provide a mechanism for reporting such errors.

And if we move the Profiles's definition to the bottom of the file, then it will be considered as a valid yaml file, and configtxgen succeed.

I am facing this issue when running node createTradeapp,js after starting the network using trade.sh,

please find the attached screenshot, here is the stack trace:

Hi,

I try to understand from the book and exercises on understanding implementation of BFT consensus in hyperledger. So far i don't find any satisfactory explanations. I've found the explanation in the book is rather brief or i have misunderstood something. Could you give some pointers on this?

thanks.

then i got the above-mentioned errors..

Any suggestion on the cause of this error?

sugamxp@sugamxp:~/go/src/trade-finance-logistics/network$ cryptogen generate --config=./crypto-config.yaml
cryptogen: command not found

Please help

executing the command
trade-finance-logistics/network/ # ./trade.sh up -d true
gives me no error but only starts the chaincode and orderer containers(as docker container ls shows me). So I am unable to follow chapter 4 in the Book. How to resolve this? Is there any way to start the missing peer and cli containers?

trade-finance-logistics.txt

i think i did everything by the book. and all the docker images are booted up. it looks somethings is wrong with "grpc".
@VRamakrishnaSG @ldesrosi @VRamakrishna .
would you have time to take a look? thanks.

This is a placeholder. Need to note down symptoms and repro method.

I am working with release-1.4, and focused on ABAC, using the ABAC.md page, specifically https://github.com/HyperledgerHandsOn/trade-finance-logistics/blob/release-1.4/chaincode/abac.md

I am running in dev mode as per Chapter 4 in the book. I believe that I am faithfully following the instructions about running " /opt/trade/createIdentity.sh" in the cli container.

However, when I attempt to invoke a trade request from the cli, presumably with the identity of "admin", it turns out that the creatorOrg, creatorCertIssuer are 'DevOrgMSP' and 'ca.devorg.trade.com'.

If I execute "export CORE_PEER_MSPCONFIGPATH=/root/.fabric-ca-client/importer" in the CLI and again invoke a trade request, it turns out that again the creatorOrg, creatorCertIssuer are 'DevOrgMSP' and 'ca.devorg.trade.com'.

Do you have any ideas what I am doing wrong or missing?

BTW, another small question is: If I follow your instructions using trade_workflow_v1, and then on page 106 I perform the two invoke steps, it turns out they are executed in test mode. But if I make a slight edit (or no edit) to tradeworkflow.go in my local machine and upload into the chaincode container and re-build go and etc, and then I perform the invoke steps, they are NOT in test mode anymore. How are you magically having it start in test mode the first time, but not after re-loading tradeworkflow.go.

Thanks

Make this code compatible with the following Fabric components:

• Fabric: https://github.com/hyperledger/fabric/tree/release-1.2
• Fabric-CA: https://github.com/hyperledger/fabric-ca/tree/release-1.2
• Fabric-SDK-Node: https://github.com/hyperledger/fabric-sdk-node/tree/release-1.2

Currently, we need to use curl commands to exercise the web application wrapping the middleware and chaincode. Notifications of transaction commitment events can only be tracked by observing console logs. It would be useful and more user-friendly to build a basic JavaScript GUI (or set of GUIs) that can enable users to orchestrate trades, and notify users of ledger state changes using websockets.

Not able to get the desired output while running the app.js on browser.
Please suggest, what is going wrong here.

Getting error when running node createTradeApp.js

• Docker containers are up and running.
• Dependencies are correct.

I had to change it to

var

_commonProto = grpc.load(path.join(__dirname, '**../application/**node_modules/fabric-client/lib/protos/common/common.proto')).common;
var _configtxProto = grpc.load(path.join(__dirname,

'../application/node_modules/fabric-client/lib/protos/common/configtx.proto')).common;

to make it work. Please consider it if it is valid for all. Thanks

Now there are four org in the network. But as to every org, there are a number of entities. For each client, it should be assigned to a specified role and a specified identity, i.e. entity of exporter, importer, exporter bank, importer bank, regulator or carrier. If the client of a given importer wants to query all the assets of him, how to do it? It seems easy to identify the role but uneasy to identify the identity of the client.
And why set the identity when instantiating the chaincode? Does this mean there is only one instance for each role?
Thanks.

We should use the Mocha framework to create proper (regression) test scripts in the middleware and application folders.

Create a file called API.md in the chaincode folder, containing a listing of all chaincode functions, their expected arguments lists', and respective access constraints. Create listings for both versions of the chaincode.

Sir,
We are working on this project. When we are trying to execute the createTradeApp.js in the middleware, we are getting the chaincode invocation failure error.

And we are running the Fabric version 1.1

We request you to help in this issue.

Thanks.

Failing to build chaincode from the root directory. But I'm able to do the go build in trade_workflow directory manually.

Hello Sir,
Hello again. I am back to this work after a long break of reading up on energy related papers.
I want to work on incremental changes in my chaincode, deploy and test it to see consensus happening.

Following is what I do -

I installed and instantiated the chaincode with v0 on the ledger.

curl -s -X POST http://localhost:4000/chaincode/instantiate -H "authorization:Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJleHAiOjE1MzM4OTQ4OTIsInVzZXJuYW1lIjoiYWRtaW4iLCJvcmdOYW1lIjoidXRpbGl0eW9yZyIsImlhdCI6MTUzMzg5MDc1Mn0.ckS82mBlP424VmiKRZlpZPVwdlcop5YEc72fBwVJv-s" -H "content-type: application/json" -d '{"ccpath": "github.com/utility_workflow", "ccversion": "v0", "args": ["2kmqtt", "100", "REQUESTED"]}'
{"success":true,"message":"Chaincode instantiated"}

Now i wish to upgrade the chaincode. I have two docker containers created with the dev prefix for running the chaincode.

I copy the same code to another directory and rename it with a suffix v1 and
run the command

curl -s -X POST http://localhost:4000/chaincode/upgrade -H "authorization:Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJleHAiOjE1MzYyNzgwMzQsInVzZXJuYW1lIjoiYWRtaW4iLCJvcmdOYW1lIjoidXRpbGl0eW9yZyIsImlhdCI6MTUzNjI3Mzg5NH0.CV4rjs-QgA1G62D7OGbwQz98n2Ydr_1T8SB5khJlm40" -H "content-type: application/json" -d '{"ccpath": "github.com**/utility_workflow_v1"**, "ccversion": "v1", "args": ["2kmqtt", "100", "REQUESTED"]}'
{"success":false,"message":"Failed to send install Proposal or receive valid response from org consumerorg: [object Object]"}

The error messages are on the node.js terminal are as follows. I have changed the config_upgrade.json and constants.json in the middleware to accomodate my network

My constants.js refers to : module.exports = {
networkConfig: networkConfig, (which is config.json and not config_upgrade.json)
And install-chaincode .js has
module.exports.installChaincode = installChaincode;

Is there some configuration that i need to change to make upgrade work using the middleware (i also tried deleting the image and containers created by the install and instantiate of the first version of chaincode)?

The error messages are below:

Hello, the instructions in the book have not been clear on the non-dev mode. I have been stuck in this part since a few days. I am new to GO, so am not clear, how the vendoring should happen.

I have a few errors that I am aware of but not sure how to solve them.

/trade_workflow$ go version
2018-07-29 11:34:52.889 IST [shim] SetupChaincodeLogging -> INFO 001 Chaincode log level not provided; defaulting to: INFO
2018-07-29 11:34:52.889 IST [shim] SetupChaincodeLogging -> INFO 002 Chaincode (build level: ) starting up ...
Error starting chaincode error chaincode id not provided

In the tradeWorkflow.go file, I get
Cannot use 'twc' (type "demandresponsepoc/chaincode/src/github.com/trade_workflow".*TradeWorkflowChaincode) as type "demandresponsepoc/chaincode/src/github.com/trade_workflow/vendor/github.com/hyperledger/fabric/core/chaincode/shim".Chaincode more... (Ctrl+F1)
This is due to improper vendoring but the directory paths to be followed for vendoring is not easy to follow and I could not install vendor.

On the blockchain terminal, I get

Any help in this would be great. I followed the book and that explained to me a lot that was not clear to me from the fabric docs.

Looking forward to your help.

Thanks

Hello,

I didn't manage to run successfully the application createTradeApp.js.
My environment is the following

• Ubuntu Version 16.04

• Nodejs set to 9.8.0 as per README

• Hyperledger branch 1.1

• the versions of both fabric-client and fabric-ca-client installed are "1.1.2" and grpc "1.10.1

• I run successfully the Dev environment exercise .

• For the 9 container JS application I applied the following steps

• Delete client_certs, channel-artifacts, crypto-config folders in network
  ./trade.sh generate -c tradechannel within network to generate the channel and crypto material
  ./trade.sh up to start the network ( the 9 containers indeed start)
  node createTradeApp.js

the error is

CHANNEL JOIN FAILED: TypeError: Cannot read property 'stack' of undefined

Please help , I strongly want to learn from your book.
Thanks

Hello,

After having some difficulty following and executing the commands in the book on my instance of Ubuntu 16.04, I decided to attempt to follow the GitHub documentation. Unfortunately, after running "./trade.sh generate -c tradechannel" inside the network folder, I get:

$ ./trade.sh generate -c tradechannel
Generating certs and genesis block with channel 'tradechannel'
Continue? [Y/n] Y
proceeding ...
cryptogen tool not found. exiting

I believe I followed all of the setup as written, as well, I ran make configtxgen cryptogen configtxlator in the fabric directory, as well as export PATH=$PATH:$GOPATH/src/github.com/hyperledger/fabric/build/bin to add it to the PATH. To double-check, I ran the make command again and got:

$ make configtxgen cryptogen configtxlator
make: Nothing to be done for 'configtxgen'.
make: Nothing to be done for 'cryptogen'.
make: Nothing to be done for 'configtxlator'.

Is there something wrong I might be doing? Sorry if there's something obvious I'm overlooking, I am new to using Docker. Thank you!

Hi

I ran the following curl command

curl -s -X POST http://localhost:4000/channel/join -H "authorization: Bearer auth-token"

I am getting the following error.

{"success":false,"message":"Cannot read property 'stack' of undefined"}

When I checked the error I am getting the following. Am I missing something.
