Blockchain network hyperledger fabric - client application cannot connect to peer

Question

I use application client nodejs to connect peer in blockchain network hyperledger fabric, but not action. Please help me

Connect file json:

    "name": "test-network",
    "version": "1.0.0",
    "client": {
        "tlsEnable": true,
        "enableAuthentication": true,
        "organization": "MyOrg",
        "connection": {
            "timeout": {
                "peer": {
                    "endorser": "300"
                },
                "orderer": "300"
            }
        }
    },
    "channels": {
        "mychannel": {
            "peers": {
                "peer-dev.peer.hc.org": {}
            }
        }
    },

        "MyOrg": {
            "mspid": "MyOrg",
            "adminPrivateKey": {
                "path": "/path/to/fabric_config/users/adminMsp/keystore/1_sk"
            },
            "peers": [
                "peer-dev.peer.hc.org"
            ],
            "signedCert": {
                "path": "/path/to/fabric_config/users/adminMsp/signcerts/cert.pem"
            }
        }
    },
    "peers": {
        "peer-dev.peer.hc.org": {
            "tlsCACerts": {
                "path": "/path/to/fabric_config/tls/ca.crt"
            },
            "url": "grpcs://peer-dev.peer.hc.org:7051"
        }
    }
}

Code client connect

const ccpPath = path.resolve('path/to/connect.json');
const contents = fs.readFileSync(ccpPath, 'utf8');
const ccp = JSON.parse(contents);
const gateway = new Gateway();

const gatewayOpts = {
  identity: {
    credentials: {
      certificate: wallet.certificate,
      privateKey: wallet.privateKey
    },
    mspId: "MyOrg",
    type: "X.509",
    version: 1
  },
  discovery: {
    enabled: true,
    asLocalhost: false
  },
};

try {
  await gateway.connect(ccp, gatewayOpts);
  const network = await gateway.getNetwork('mynetwork'); // -> ERROR HERE
  const contract = network.getContract('mycontract');
} finally {
  gateway.disconnect();
}
