Common connection profile missing error while adding user for organization

问题

I am getting

Error: Common connection profile is missing this client's organization and certificate authority 

Error, while running gateway.getClient().getCertificateAuthority() code line. My connection profile file is there and as per my understanding it has no issues.

Following is my nodejs client code.

'use strict';

const { FileSystemWallet, Gateway, X509WalletMixin } = require('fabric-network');
const path = require('path');

const ccpPath = "../connection-ogr4.json";

async function main() {
    try {

        let user = 'user2';
        // Create a new file system based wallet for managing identities.
        const walletPath = path.join(process.cwd(), 'wallet');
        const wallet = new FileSystemWallet(walletPath);
        console.log(`Wallet path: ${walletPath}`);

        const userExists = await wallet.exists(user);

        // Check to see if we've already enrolled the admin user.
        const adminExists = await wallet.exists('admin');

        // Create a new gateway for connecting to our peer node.
        const gateway = new Gateway();
        await gateway.connect(ccpPath, { wallet, identity: 'admin', discovery: { enabled: true, asLocalhost: true } });
        // Get the CA client object from the gateway for interacting with the CA.
        const ca = gateway.getClient().getCertificateAuthority()

It uses the following connection json file.

{
"name": "network-org4",
"version": "1.0.0",
"client": {
    "organization": "Org4",
    "connection": {
        "timeout": {
            "peer": {
                "endorser": "300"
            }
        }
    }
},
"organizations": {
    .......
},
"certificateAuthorities": {
    "ca.org4.bc4scm.de": {
        "url": "https://localhost:9054",
        "caName": "ca-org4",
        "tlsCACerts": {
            "path": "crypto-config/peerOrganizations/org4.bc4scm.de/tlsca/tlsca.org4.bc4scm.de-cert.pem"
        },
        "httpOptions": {
            "verify": false
        }
    }
}

}

What is the reason for this issue? Appreciate your insights.

There might be "channels", orderers, peers ,missing.For more insight you could refer - https://fabric-sdk-node.github.io/tutorial-network-config.html Meanwhile below is the running snippet, you only need to change the configuration according to your network.
