x509: ECDSA verification failure

Question

I have to install a bna file on fabric . I am following the link https://hyperledger.github.io/composer/tutorials/deploy-to-fabric-single-org.html . However when I run the command: composer runtime install -c PeerAdmin@fabric-network -n tutorial-network

I am getting the error :

Error: Error trying install composer runtime. Error: No valid responses from any peers.

Response from attempted peer comms was an error:

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").

Any help on this please

Answer 1

sounds like you have made an error in following the tutorial (which definitely works). Are you sure the MSP id (Org1MSP) for the peer has been setup correctly ? Have you checked that the peer has successfully joined the channel (when the Fabric was started)? Have you done a docker ps to see your Fabric docker containers are running?) Assuming you followed the steps correct and using an identity you have obtained from a fabric-ca server (per the tutorial), have you checked the fabric-ca server is running correctly (docker logs ? Also, is it possible you're restarted your Fabric docker environment at one point and now your old key information is invalid?

eg

{ "name": "fabric-network", "type": "hlfv1", "mspID": "Org1MSP", "peers": [ { "requestURL": "grpc://localhost:7051", "eventURL": "grpc://localhost:7053" } ], "ca": { "url": "http://localhost:7054", "name": "ca.org1.example.com" }, "orderers": [ { "url" : "grpc://localhost:7050" } ], "channel": "composerchannel", "timeout": 300 }

then re-create the card with the correct key/signcert info

composer card create -p connection.json -u PeerAdmin -c Admin@org1.example.com-cert.pem -k xxxxx_sk -r PeerAdmin -r ChannelAdmin

where the .pem file comes from signcerts directory and xxxxx is the generated value for the key filename in keystore.
