LSCC must issue at least one single putState upon deploy/upg

Error message

LSCC must issue at least one single putState upon deploy/upgrade

What it means

A policy validation failure in LSCC validation logic (v1.3 built-in VSCC) for deploy/upgrade transactions: after parsing the LSCC write-set, there are zero putState writes, so the rwset does not contain the chaincode data (and collections/config) writes that a legitimate LSCC deploy or upgrade must perform. It indicates a malformed or tampered LSCC invocation rather than an internal ledger error.
