How to solve x509 ECDSA verification failure error

+1 vote

I am trying to run the 

composer runtime install -c PeerAdmin@fabric-network -n tutorial-network 

command

And I get the following error:

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")

How to solve this?

Before you execute the 

composer runtime install -c PeerAdmin@fabric-network -n tutorial-network 

command, check the following:

1. Has the peer setup correctly?

2. Has the peer joined the channel?

3. Is fabric-ca running?

If all this is fine and you are still facing the problem then try this code:

{

"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

}

And then re-create the card like this:

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

You are getting this error probably because fabric is not running. 

Check if fabric is running. You can use the following command for that:

$ docker ps

and if it is not running then start it using:

$ ./startFabric.sh

Peers are not sending a response. Try restarting the fabric:

$ ./stopFabric.sh
$ ./startFabric.sh

I was facing the same issue and it was because I had not created peer cards. So, creating the cards for peers solved my problem. First, start the network and then create the card (code mentioned below):

$ ./startFabric.sh
$ ./createPeerAdminCard.sh

This error is because fabric is not properly configured. The solution is to run the below mentioned commands:

./stopFabric.sh
export FABRIC_VERSION=hlfv11
./startFabric.sh
./createPeerAdminCard.sh
install network
start network

Seems like runtime dependencies are missing. Try this:

$ export FABRIC_VERSION=hlfv11
$ ./startFabric.js
$ composer runtime install

I solved this error by adding the following lines to the createPeerAdmin.sh file.

"peer0.org1.example.com": {
                    "endorsingPeer": true,
                    "chaincodeQuery": true,
                    "eventSource": true
                },

I am new to this so I don't know what this does.
