I m working on hyperledger blockchain and Kubernetes(minikube) on Ubuntu 18-04. In my network there two Organisations with one peer each and the orderer type is Solo. This whole network I deployed on minikube. Chaincode install and instantiation did successfully on pods. After that am trying to invoke by using SDK.
I am using the below code as invoke.js
'use strict';
const { Gateway, Wallets } = require('fabric-network');
const fs = require('fs');
const path = require('path');
async function main() {
try {
// load the network configuration
const ccpPath = path.resolve(__dirname, '..', '..', 'first-network', 'connection1-org1.json');
let ccp = JSON.parse(fs.readFileSync(ccpPath, 'utf8'));
// Create a new file system based wallet for managing identities.
const walletPath = path.join(process.cwd(), 'wallet');
const wallet = await Wallets.newFileSystemWallet(walletPath);
console.log(`Wallet path: ${walletPath}`);
// Check to see if we've already enrolled the user.
const identity = await wallet.get('user1');
if (!identity) {
console.log('An identity for the user "user1" does not exist in the wallet');
console.log('Run the registerUser.js application before retrying');
return;
}
// Create a new gateway for connecting to our peer node.
const gateway = new Gateway();
await gateway.connect(ccp, { wallet, identity: 'user1',discovery: { enabled: true, asLocalhost: true } });
// Get the network (channel) our contract is deployed to.
const network = await gateway.getNetwork(channelname);
// Get the contract from the network.
const contract = network.getContract(contractname);
// Submit the specified transaction.
// createCar transaction - requires 5 argument, ex: ('createCar', 'CAR12', 'Honda', 'Accord', 'Black', 'Tom')
// changeCarOwner transaction - requires 2 args , ex: ('changeCarOwner', 'CAR10', 'Dave')
await contract.submitTransaction('arumnet','argument');
console.log('Transaction has been submitted');
// Disconnect from the gateway.
await gateway.disconnect();
} catch (error) {
console.error(`Failed to submit transaction: ${error}`);
process.exit(1);
}
}
main();

Some things to check:
connection1-org1.json - you've supplied connection1-org1.json in the code for invoke.js but connection.json config as a candidate you presumably expect to be used to load/access the network. Pls confirm if this is correct.connection.json - specifies a tlsCACerts but the url scheme used is grpc:// rather than grpcs://If you can confirm/amend as necessary it will provide a better chance for someone to help.
