GetChaincodeAction error %s

Error message

GetChaincodeAction error %s

What it means

Returned by ValidateLSCCInvocation when protoutil.UnmarshalChaincodeAction fails on the proposal response payload's extension bytes. The chaincode action (which must contain the tx rwset) cannot be decoded, so VSCC aborts the validation.
