I combined grpc and pika in a Class but I got problem both in client and server of my system when a grpc function in client get start.
The client got grpc Exception calling application, the server got rabbitmq pop from an empty deque.
And I found rabbitmq-server log, client tcp was unexpectedly closed.

Here is traceback of my client:

Traceback (most recent call last):
  File "/home/jason/anaconda3/envs/chatroom/lib/python3.9/tkinter/__init__.py", line 1892, in __call__
    return self.func(*args)

    result = self.clientrpc.login()

    res = self.stub.myLogin(helloworld_pb2.LoginRequest(username=self.username, password=self.password, queuename=self.queue_name)).res

        details = "Exception calling application: Stream connection lost: IndexError('pop from an empty deque')"
        debug_error_string = "UNKNOWN:Error received from peer  {grpc_message:"Exception calling application: Stream connection lost: IndexError('pop from an empty deque')", grpc_status:2, created_time:"2024-06-18T20:12:40.624492156+08:00"}"

And here is the traceback of my server:

Exception has occurred: StreamLostError

  File "/home/jason/codes/TalkyWalky/server_rpc.py", line 135, in receive

  File "/home/jason/codes/TalkyWalky/server_rpc.py", line 119, in connect
    self.receive()
pika.exceptions.StreamLostError: Stream connection lost: IndexError('pop from an empty deque')

And here is rabbitmq Server log:

2024-06-18 20:34:20.096125+08:00 [warning] <0.28361.0> client unexpectedly closed TCP connection

I do confirm, rabbitmq and grpc use different ports

I have no idea what i could try.
