我想发送一个请求,使用问模式的远程演员。当地的演员会收到一些价值,并在它上面执行一些任务并更新它。 然后,当本地演员尝试发送更新值给远程演员时,发送时发生错误。我应该如何处理这个错误?斯卡拉阿卡演员,问模式,发送答复时遇到的死信

Remote Actor:
class RemoteActor() extends Actor {

是的,我已经更新了发信人瓦尔currentSender,但仍存在着同样的错误,因为第一次调用是从LocalActor到RemoteActor,然后本地回复远程等待:案例TaskLA1 (taskA)=> val rCxt = remoteActor? TaskFromLocal()val currentSender = sender rCxt.onComplete {0}成功(Rcvdcxt(cxtA))=> currentSender! Rcvdcxt(cxtA) ... } –
