VSCC error: committing an invocation of function %s of lscc

Error message

VSCC error: committing an invocation of function %s of lscc is invalid

What it means

The LSCC function name in the invocation is not one of the recognized operations (deploy, upgrade, etc.), so committing this LSCC invocation is invalid — likely a tampered or client-unsupported function.
