Worker ${this.id} is terminated

Error message

Worker ${this.id} is terminated

What it means

WorkerInstance.execute was invoked after the worker reached the 'terminated' status. A terminated worker has been torn down and cannot accept tasks, so any queued or in-flight dispatch to this worker id is rejected as an illegal lifecycle use.
