My API code below:
// create mychannel instance
let channel = new Channel('mychannel', client1);
// get certificates from couchdb wallet
let couchdbWallet = await Wallets.newCouchDBWallet("http://xxxxx:xxxxxxx#localhost:5984");
let user5 = await couchdbWallet.get('user5');
if (user5) {
let user5Cert = user5.credentials.certificate;
let user5Key = user5.credentials.privateKey;
let mspId = 'org1MSP';
await client1.initCredentialStores();
let cryptoSuite = client1.getCryptoSuite();
let keyObj = await cryptoSuite.importKey(user5Key);
let user5PubKey = keyObj._key.pubKeyHex;
let user5PrvKeyHex = keyObj._key.prvKeyHex;
let signer = new Signer(cryptoSuite, keyObj);
// create instance of signing identity
let signingIdentity = new SigningIdentity(
user5Cert,
user5PubKey,
'org1MSP',
cryptoSuite,
signer
);
// 1. generate unsigned transaction proposal
let transactionProposal = {
fcn: 'Mint',
args: ['1000'],
chaincodeId: 'token-erc-20',
channelId: 'mychannel'
}
let { proposal, txId } = await channel.generateUnsignedProposal(
transactionProposal,
mspId,
user5Cert,
true
);
console.log('*******proposal*****:\n', proposal);
console.log('*******Tx Id******\n', txId);
// now we have the 'unsigned proposal' for this tx
// 2. calculate the hash of the tx proposal bytes
let proposalBytes = proposal.toBuffer(); // the proposal comes from step 1
// 3. calculate the signature for this tx proposal
let signedProposal = signingIdentity.sign(proposalBytes);
console.log('********signedProposal********\n:', signedProposal);
// 4. send the signed tx proposal to peer(s)
let tlscaRootCert = readFileSync(tlscaRootCertPATH, { encoding: 'utf-8' });
console.log('tlscaRootCert: ', typeof tlscaRootCert);
let peer1org1 = client1.newPeer('grpcs://172.19.0.9:7051',
{
pem: tlscaRootCert,
}
);
let targets = new Array();
targets.push(peer1org1);
let sendSignedProposalReq = { signedProposal, targets };
let proposalResponses = await channel.sendSignedProposal(sendSignedProposalReq);
// check the proposal responces, if all good, commit the tx
// 5. similar to step 1, generate an unsigned tx
let commitReq = {
proposalResponses,
proposal,
};
let commitProposal = await channel.generateUnsignedTransaction(commitReq);
/// 6. similar to step 3, sign the unsigned tx with the user's private key
let commitProposalBytes = commitProposal.toBuffer();
let signedCommitProposal = signingIdentity.sign(commitProposalBytes);
// 7. commit the signed tx
let response = await channel.sendSignedTransaction({
signedTransaction: signedCommitProposal,

});
console.log('**********response from orderer after commit signed tx********\n', response);
// response.status should be 'SUCCESS' if the commit succeed
if (response.status === 'SUCCESS') {
// connect to event channel hub
let eventChannelHub = new ChannelEventHub(channel);
// 8. similar to step 1, generate an unsigned eventHub registration for the ChannelEventHub
let unsigneEvent = eventChannelHub.generateUnsignedRegistration({
certificate: user5Cert,
mspId
});
// 9. similar to step 3, sign the unsigned eventhub registration with the user's private key
let unsignEventBytes = unsigneEvent.toBuffer();
let signedEvent = signingIdentity.sign(unsignEventBytes);
// 10. register this ChannelEventHub at peer
let connectEventChannel = eventChannelHub.connect({ signedEvent });
console.log('***********connectEventChannel*********\n', connectEventChannel);
}
}
I try to submit transaction.
But every time I receive this error:
docker-compose.yaml logs
2022-09-21T11:36:52.296Z - error: [Channel.js]: Error: 14 UNAVAILABLE: failed to connect to all addresses
peer1-org1 container logs:

Also I receive this error now:
2022-09-21T13:01:10.858Z - error: [Channel.js]: sendTransaction - no valid endorsements found
How can I resolve this problem?

Answer 1

From peer logs, it seems like transaction submitter is not having access to the channel. Make sure the user identify is valid and the user's organization joined the channel. This error may come also if the MSP name given is wrong. MSP name is case sensitive.
