Hyperledger Fabric Promise is rejected Error Failed to deserialize creator identity The supplied identity is not valid

Question

I started all the containers using this command:

./startFabric.sh

It works fine but when I use the command

node query.js

I get the following error:

Set wallet path, and associate user PeerAdmin with application Check user is enrolled, and set a query URL in the network Make query Assigning transaction_id: 27d48de27350bbeeb3adae69ec5e783d3af1c42af03230877f71c3343bfbc905 error: [client-utils.js]: sendPeersProposal - Promise is rejected: Error: Failed to deserialize creator identity, err The supplied identity is not valid, Verify() returned x509: certificate signed by unknown authority (possibly because of "x509: ECDSA verification failure" while trying to verify candidate authority certificate "ca.org1.example.com") at /home/eres_admin/hyperledger/fabric-samples/fabcar/node_modules/grpc/src/node/src/client.js:554:15 returned from query Query result count = 1 error from query = { Error: Failed to deserialize creator identity, err The supplied identity is not valid, Verify() returned x509: certificate signed by unknown authority (possibly because of "x509: ECDSA verification failure" while trying to verify candidate authority certificate "ca.org1.example.com") at /home/eres_admin/hyperledger/fabric-samples/fabcar/node_modules/grpc/src/node/src/client.js:554:15 code: 2, metadata: Metadata { _internal_repr: {} } } Response is Error: Failed to deserialize creator identity, err The supplied identity is not valid, Verify() returned x509: certificate signed by unknown authority (possibly because of "x509: ECDSA verification failure" while trying to verify candidate authority certificate "ca.org1.example.com")

Answer 1

 This error happens because basic-network/docker-compose.yaml has CA key hardcoded. If you re-generate the cryptomaterial, the key file name changes. Thus the CA fails to find the key.

After you regenerate the crypto material you should change the FABRIC_CA_SERVER_CA_KEYFILE

...
services:
  ca.example.com:
    image: hyperledger/fabric-ca
    environment:
      - FABRIC_CA_HOME=/etc/hyperledger/fabric-ca-server
      - FABRIC_CA_SERVER_CA_NAME=ca.example.com
      - FABRIC_CA_SERVER_CA_CERTFILE=/etc/hyperledger/fabric-ca-server-config/ca.org1.example.com-cert.pem
      - FABRIC_CA_SERVER_CA_KEYFILE=/etc/hyperledger/fabric-ca-server-config/4239aa0dcd76daeeb8ba0cda701851d14504d31aad1b2ddddbac6a57365e497c_sk
