我有一个 c＃客户端和服务器，并在客户端中调用Grpc.Core.RpcException函数时从Status(StatusCode=Unknown, Detail="Exception was thrown by handler.")中收到类型为SendMessage的类型为Got response: True
RPC failed Grpc.Core.RpcException: Status(StatusCode=Unknown, Detail="Exception was thrown by handler.")

的未处理异常（由 proto 文件）。
堆栈跟踪为：
sendMessage proto 文件中的service MessageService{
rpc SendMessage(Message) returns (Empty){}
}
message Message{
bytes msg = 1;
int32 senderId = 2;
int32 receiverId = 3;
}
message Empty {}
方法如下：
SendMessage 客户端中的public void SendMessage(String msg, int receiverId)
{
try
{
client.SendMessage(NewMsg(msg, ID, receiverId)); //this is where it gets stuck
Log("sending: ", msg);
}
catch (RpcException e)
{
Log("RPC failed " + e);
throw;
}
}
实现：
public override Task<Empty> SendMessage(Message request, ServerCallContext context)
{
try
{
Task<Empty> empty = null;
messages.Add(request);
return empty;
}
catch (RpcException e){
Console.WriteLine("Remote procedure call failed: " + e);
throw;
}
}
方法的服务器端实现：
