VSCC error: invocation of lscc(%s) does not have appropriate

Error message

VSCC error: invocation of lscc(%s) does not have appropriate arguments

What it means

Structural check failed on the invocation artifacts: the CDS, its ChaincodeSpec/ChaincodeId, the cap.Action, or the ProposalResponsePayload is nil — required pieces of the endorsement are missing, so validation cannot continue.
