Chaincode install error

[ghost]

Hi I am getting error when installing marble chaincode in my local hyperledger network.

Error : sendPeersProposal - Promise is rejected: Error: 2 UNKNOWN: Stream removed Failed to obtain endorsement for transaction. code=2, , details=Stream removed

Please help me to resolve this issue.

Note : Docker version- 1.13.1 fabric_version 1.1.0

I haven't seen this one before, this grpc issue might be of help: https://github.com/grpc/grpc-node/issues/130

people seem to fix it by changing their grpc version. check out what version you have running by opening the file /node_modules/grpc/package.json, marbles should be using version 1.10.1

This problem is related to the use of grpc instead od grpcs.

You can correct it by changing grpc to grpcs in your code when you use nodejs SDK. If you do this, you will find a PEM error. To correct it you should add other arguments to "newPeer(...)" function.

you can adapt this piece of code to your code where you use the "newPeer" function and if you use the newOrderer function add the changes in the same way as newPeer.

code: to add and modify:

var fs = require('fs'); var path = require('path');

var firstnetwork_path = path.resolve('..', '..', 'first-network'); var org1tlscacert_path = path.resolve(firstnetwork_path, 'crypto-config', 'peerOrganizations', 'org1.example.com', 'tlsca', 'tlsca.org1.example.com-cert.pem'); var org1tlscacert = fs.readFileSync(org1tlscacert_path, 'utf8');

// var fabric_client = new Fabric_Client();

// setup the fabric network var channel = fabric_client.newChannel('mychannel'); var peer = fabric_client.newPeer('grpcs://localhost:7051', { 'ssl-target-name-override': 'peer0.org1.example.com', pem: org1tlscacert }); channel.addPeer(peer);

Thanks @oumaima1234. That did the trick. I didn't end up needing ssl-target-name-override as the cert matched the dns name.
