Failed to submit transaction: Error: no suitable peers available to initialize from

Question

I am running my blockchain project which is election system using blockchain using hyperledger fabric and IBM blockchain Platform VSCode Extension (runnning my network locally). I am successfull to run connect to local fabric and my gateway is running successfully(image attached). Also all docker containers of peer,orderer,certificate authority are running (image attached).

connected to local fabric and gateway

all docker containers running successfuly

The problem which I am facing is that when (after connecting to local fabric and gateway) I am running invoke.js file using the command "node invoke.js" I am encountering above error. following picture link shows how I am running invoke.js

trying to run invoke.js but facing error

following is my config.json file code

    {
  "connection_file": "fabric_connection.json",
  "appAdmin": "admin",
  "appAdminSecret": "adminpw",
  "orgMSPID": "org1MSP",
  "caName": "ca",
  "userName": "V1",
  "gatewayDiscovery": { "enabled": true, "asLocalhost": true }
}

and following is my fabric-connection.json file code

{
    "certificateAuthorities": {
        "ca.org1.example.com": {
            "caName": "ca",
            "url": "http://localhost:17090"

    },

    },

        }
    },
    "version": "1.0.0"
}

and following is my invoke.js file complete code

//Import Hyperledger Fabric 1.4 programming model - fabric-network
'use strict';

const { FileSystemWallet, Gateway } = require('fabric-network');
const path = require('path');
const fs = require('fs');

//connect to the config file
const configPath = path.join(process.cwd(), './config.json');
const configJSON = fs.readFileSync(configPath, 'utf8');
const config = JSON.parse(configJSON);

// connect to the connection file
const ccpPath = path.join(process.cwd(), './ibpConnection.json');
const ccpJSON = fs.readFileSync(ccpPath, 'utf8');
const connectionProfile = JSON.parse(ccpJSON);

// A wallet stores a collection of identities for use
const walletPath = path.join(process.cwd(), './wallet');
const wallet = new FileSystemWallet(walletPath);
console.log(`Wallet path: ${walletPath}`);

const peerIdentity = 'admin';

async function queryAll() {
  
  try {

    let response;

    // Check to see if we've already enrolled the user.
    const userExists = await wallet.exists(peerIdentity);
    if (!userExists) {
      console.log('An identity for the user ' + peerIdentity + ' does not exist in the wallet');
      console.log('Run the registerUser.js application before retrying');
      response.error = 'An identity for the user ' + peerIdentity + ' does not exist in the wallet. Register ' + peerIdentity + ' first';
      return response;
    }

    //connect to Fabric Network, but starting a new gateway
    const gateway = new Gateway();

    //use our config file, our peerIdentity, and our discovery options to connect to Fabric network.
    await gateway.connect(connectionProfile, { wallet, identity: peerIdentity, discovery: config.gatewayDiscovery });

    //connect to our channel that has been created on IBM Blockchain Platform
    const network = await gateway.getNetwork('mychannel');

    //connect to our insurance contract that has been installed / instantiated on IBM Blockchain Platform
    const contract = await network.getContract('voteChainDemo'); 
    //submit transaction to the smart contract that is installed / instnatiated on the peers
    console.log('calling contract.evaluateTransaction, with args');
    response = await contract.submitTransaction('queryAll');
    response = JSON.parse(response.toString());
    console.log(`response from evaluateTransaction: ${(response)}`)
   

    console.log('Transaction has been submitted');

    // Disconnect from the gateway.
    await gateway.disconnect();

  } catch (error) {
    console.error(`Failed to submit transaction: ${error}`);
  }
}
// let args = ["V1"]
// args = args.toString();
queryAll();

and I see following logs when I view docker container logs of peer0.org1.example.com

Can you please show you connection config and the relevant part of invoke.js where the exception is thrown. Also, can you see any reaction in the peer container's logs? — Tho Mai, Aug 21 '20 at 06:37
sure, I have modified the question and provided config.json, local-fabric.json and invoke.js code — Dijkstra Algorithm, Aug 21 '20 at 08:32
why can't the peer connect to the orderer? any hints in the orderer log? — Tho Mai, Aug 21 '20 at 10:38
can't figure out. I think the issue is in ibpconnection.json file which I have added now in the question. — Dijkstra Algorithm, Aug 21 '20 at 11:46
just for completeness: did you check that you can ping the orderer and connect to the port with netcat or the like? — Tho Mai, Aug 21 '20 at 14:46

In my project which is pretty much having the same things as you, I did not specified the orderers in my connection config file. I am not sure if it is required in your scenario.

Besides, I think the issue is caused by incorrect urls specified in your ibpconnection.jsonfile.

orderers should have "url": "grpcs://173.193.112.109:7050"

AND

peers should have "url": "grpcs://173.193.112.109:17091"

Hope this will fix the error. Good luck!!!!

Also, maybe change: `"ssl-target-name-override": "173.193.112.109"` to `"ssl-target-name-override": "peer0.org1.example.com"` – jasonph Aug 28 '20 at 05:07
