I am trying to create a single org, single ca, single peer network, bootstrapped by the nodejs-sdk. I have used this sample for reference.
When I try to instantiate() the chaincode I get this error in the peer accessed by docker logs ax-peer

No additional logs are being registered by the orderer. My code is as follows
const createClientInstance = async () => {
let myClient = new client();
const ordererConfig = {
hostname: 'orderer0',
url: 'grpc://localhost:7050',
pem: readCryptoFile('ordererOrg.pem')
};
const orderer = myClient.newOrderer(ordererConfig.url, {
pem: ordererConfig.pem,
'ssl-target-name-override': ordererConfig.hostname
});
let peerConfig = {
hostname: 'ax-peer',
url: 'grpc://localhost:7051',
eventHubUrl: 'grpc://localhost:7053',
pem: readCryptoFile('axOrg.pem')
};
const defaultPeer = myClient.newPeer(peerConfig.url, {
pem: peerConfig.pem,
'ssl-target-name-override': peerConfig.hostname
});
myClient.setStateStore(await client.newDefaultKeyValueStore({
path: './ax-peer'
}))
let user = await myClient.getUserContext('admin', true);
if (user && user.isEnrolled()) {
console.log('Existing admin user used');
} else {
let url = 'http://localhost:7054'
const ca = new CAClient(url, {
verify: false
});
let enrollmentID = 'admin';
let enrollmentSecret = 'adminpw';
const enrollment = await ca.enroll({
enrollmentID: 'admin',
enrollmentSecret: 'adminpw'
});
user = new User(enrollmentID, myClient);
await user.setEnrollment(enrollment.key, enrollment.certificate, 'AxOrgMSP');
};
await myClient.setUserContext(user);
let adminUser = await myClient.createUser({
username: `Admin@ax-peer`,
mspid: 'AxOrgMSP',
cryptoContent: {
privateKeyPEM: readCryptoFile('Admin@ax-org-key.pem'),
signedCertPEM: readCryptoFile('Admin@ax-org-cert.pem')
}
});
let channelRes = await myClient.queryChannels(defaultPeer);
// Create a new channel. Does not make you join it though
let txId = myClient.newTransactionID();
let envelope_bytes = fs.readFileSync('./channel.tx');
var channelConfig = myClient.extractChannelConfig(envelope_bytes);
let signature = myClient.signChannelConfig(channelConfig);
const request = {
name: 'default',
orderer: orderer,
config: channelConfig,
signatures: [signature],
txId: txId
};
await myClient.createChannel(request);
let channel = myClient.newChannel('default');
channel.addOrderer(orderer);
channel.addPeer(defaultPeer);
const genesisBlock = await channel.getGenesisBlock({ txId: myClient.newTransactionID() });
let res = await channel.joinChannel({
targets: [defaultPeer],
txId: myClient.newTransactionID(),
block: genesisBlock
}, 120000);
const installReq = {
targets: [ defaultPeer ],
chaincodePath: ccPath,
chaincodeId:'ax-chaincode',
chaincodeVersion: 'v2',
chaincodeType: 'node'
};
let installRes = await myClient.installChaincode(installReq, 120000);
let instantiateResponse = await channel.sendInstantiateProposal({
targets: [ defaultPeer ],
chaincodeId: 'ax-chaincode',
chaincodeVersion: 'v2',
chaincodeType: 'node',
txId: myClient.newTransactionID()
});
// This fails
console.log(instantiateResponse);
};
Since the language is node I have to provide the absolute path to the chaincode. My folder structure is
- chaincode
- src
- ax-chaincode
- package.json
- index.js (fabric-contract-api used)
- server
- index.js (where I am calling the above code)
If I run client.queryInstalledChaincodes(defaultPeer) then it returns this log so I guess the chaincode is being installed.
{ chaincodes:
[ { name: 'ax-chaincode',
version: 'v2',
path: '/home/varun/Algorythmix/Core-Projects/ax-boilerplate/chaincode/src/ax-chaincode',
input: '',
escc: '',
vscc: '',
id: [Object] } ] }
How do I fix this? I want to stick to using nodejs and not change my chaincode to golang. The example also pulls the certificates and stores it in the root folder so it can be accessed without having to do docker exec -it bash.
So as per the suggestion by Gari, I added the command in my peer-base.yaml file. The code still did not work but in docker logs ax-peer a more descriptive error popped up that said fabric-chaincode-node not found. Upon inspection it seems apart from installing fabric-contract-api, I also have to install fabric-shim in the chaincode folder. This was added as a requirement in latest Fabric as per this document.
Since fabric-contract-api extends fabric-shim so I did not include it, now that I have the chaincode is being installed.
EDIT- 2020
The documents for nodejs SDK have shifted. The release notes and new dependencies for fabric-contract-api can be found at this link which states the fabric-shim is now fabric-shim-api
