GetProposalResponsePayload error %s

Error message

GetProposalResponsePayload error %s

What it means

Returned by ValidateLSCCInvocation when protoutil.UnmarshalProposalResponsePayload fails on the cap.Action.ProposalResponsePayload bytes. The endorsed payload cannot be decoded, so the rwset the LSCC invocation claims to write cannot be extracted and checked.
