txRWSet.FromProtoBytes error %s

Error message

txRWSet.FromProtoBytes error %s

What it means

Returned by ValidateLSCCInvocation when txRWSet.FromProtoBytes fails to deserialize the chaincode action's results into a read-write set. The bytes exist but are corrupt or incompatible, preventing the security checks over the LSCC writes.
