I get "NotImplementedError" using the asynchronous version of socketio

Hi @miguelgrinberg I am implementing socketio inside a discord bot. I have to use the asynchronous version of socketio because discord.py is asynchronous. Using the synchronous version of socketio everything works fine, when I use the asynchronous version the following error occurs:

Ignoring exception in command verify:
Traceback (most recent call last):
  File "C:\Program Files (x86)\Microsoft Visual Studio\Shared\Python37_64\lib\site-packages\discord\ext\commands\core.py", line 85, in wrapped
    ret = await coro(*args, **kwargs)
  File "C:\Users\gatto\OneDrive\Desktop\Python\Bot Discord CG\sub_verify.py", line 28, in verify
    await sio.connect('http://localhost:8000')
  File "C:\Users\gatto\AppData\Roaming\Python\Python37\site-packages\socketio\asyncio_client.py", line 111, in connect
    engineio_path=socketio_path)

  File "C:\Program Files (x86)\Microsoft Visual Studio\Shared\Python37_64\lib\asyncio\events.py", line 540, in add_signal_handler
    raise NotImplementedError
NotImplementedError

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "C:\Program Files (x86)\Microsoft Visual Studio\Shared\Python37_64\lib\site-packages\discord\ext\commands\bot.py", line 903, in invoke
    await ctx.command.invoke(ctx)
  File "C:\Program Files (x86)\Microsoft Visual Studio\Shared\Python37_64\lib\site-packages\discord\ext\commands\core.py", line 855, in invoke
    await injected(*ctx.args, **ctx.kwargs)
  File "C:\Program Files (x86)\Microsoft Visual Studio\Shared\Python37_64\lib\site-packages\discord\ext\commands\core.py", line 94, in wrapped
    raise CommandInvokeError(exc) from exc
discord.ext.commands.errors.CommandInvokeError: Command raised an exception: NotImplementedError:

This is my code:

import socketio
import discord
from discord.ext import commands
import time
import asyncio


data = time.strftime("%d/%m/%Y")
ora = time.strftime("%H:%M:%S")
sio = socketio.AsyncClient(logger=True, engineio_logger=True)


@sio.event()
async def url_received(data):
    print(data)
 

class Sub(commands.Cog):

    def __init__(self, bot):
        self.bot = bot


    @commands.command()
    async def verify(self, ctx):
        if ctx.message.channel.id == 749357312048758805:
            embed = discord.Embed(title="TEST", description="**TEST DESCRIPTION!**", color=0x00ff00)
            embed.set_footer(text="TEST MESSAGE | {}".format(data))
            await sio.connect('http://127.0.0.1:5000/')
            await sio.emit("URL REQUEST")
            await ctx.send(embed=embed) 

What is the cause of this? If you need more information, please ask. Thanks in advance.

Hi, I got the same error. It helped me to get back to version python-engineio-3.13.1
