hyperledger fabric invoke.js “Error: 2 UNKNOWN: access denied: channel [mychannel] creator org [Org1MSP]”

Question

I am able to invoke my chaincode from docker cli successfully (fabric-shim).
i ran enrollAdmin.js and registerUser.js sucessfully,
but when i try to run invoke.js or query.js, i get Error: 2 UNKNOWN: access denied: channel [mychannel] creator org [Org1MSP].

Answer 1

Though there are limited information shows above, the peer log give the essential hint about the problem:

WARN 044 channel [mychannel]: MSP error: the supplied identity is not valid: x509: certificate signed by unknown authority (possibly because of "x509: ECDSA verification failure" while trying to verify candidate authority certificate "ca.org1.example.com" 

Here is the suggestions that may help your to solve this problem:

1. Change your peer's logging level to DEBUG on docker-compose file, you will be more easily to find the solution followed by the debug information.
2. Make sure your CA container is running and its logs not throws out error, like some certifications verify error, which commonly causes by wrong configuration.
3. Now that the logs shows up some information about x509 ECDSA, which related to the signature and and the peers endorsement keycert. Also, this keycerts may storage on /tmp/hfc-key-store or any other place that you defined on you code. Try to clean up this temporary file and restart network again.
4. Noticed that your are using the fabric-sample repo, I think this problem may not caused by some code issues since you just modified a few parameters. So I recommend you to follow this tutorial to get the right step.

Answer 2

I came across similar issue.

I found out then channel name in network config and the channel I created was different. So I changed the channel name in the network config and it got fixed.
