Client cannot connect to server

[simplyrohan]

I have made a async server-client setup, but when I try to connect the client to the server I get an error:

This is my server setup:

import socketio
from aiohttp import web


sio = socketio.AsyncServer(async_mode="aiohttp", async_handlers=True)
app = web.Application()
sio.attach(app)

devices = {}


@sio.event
async def connect(sid, environ, auth):
    devices[sid] = 0

@sio.on("seatnum")
async def seatnum(sid, data):
    print("Seatnum")
    devices[sid] = int(data)


@sio.event
async def disconnect(sid):
    devices.pop(sid)


if __name__ == '__main__':
    web.run_app(app, host="localhost", port=5000)

And this is my client:

import socketio
import asyncio

sio = socketio.AsyncClient()


@sio.event
async def connect():
    print("Connected!")


@sio.event
async def disconnect():
    print("Disconnected")


async def main():
    await sio.connect('http://localhost:5000')

if __name__ == "__main__":
    asyncio.run(main())

The client's output is:

packet queue is empty, aborting
Connected!
Unclosed client session
client_session: <aiohttp.client.ClientSession object at 0x7faea6185fd0>
Exception ignored in: <function ClientResponse.__del__ at 0x7faea58e2af0>

  File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/asyncio/base_events.py", line 508, in _check_closed
RuntimeError: Event loop is closed

The client prints "Connected!", which indicates that it got a connect event. However the server does not reflect that.

I am at loss here. I tried making my own eventloop and changing ping_timeout, however they also returned errors of their own. If you want to see these errors, please let me know. This error has not appeared on my other servers, which are setup, from my eyes, identical.

You aren't doing anything after connecting, so the script exits. Add a sio.wait() after connecting, at least.
