handle message: invalid state %s for transaction %s

Error message

handle message: invalid state %s for transaction %s

What it means

Handler.handleMessage default-case guard: the fabric-side chaincode handler's state is neither Created nor Ready (an invalid internal state), so the message cannot be routed — indicates a handler lifecycle bug, not client input.
