Error when trying to run discord.py with asynchronous functions on cog

I am trying to build my first discord.py bot on a docker container. But when running it the traceback gave me the following error on the cogs_loader:

I used the following articles to try to fix the error, but I failed when trying refactor my code with their solution:

Bot base.load_extentstion was never awaited error message discord.py

"RuntimeWarning: coroutine 'BotBase.load_extension' was never awaited" after updating discord.py

This is my "client" file:

intents = discord.Intents.default()
bot = Bot(owner_id=env.owner_id, command_prefix='.', intents=intents)

async def load_extensions():
    await bot.load_extension('bot.cogs.commands')
    await bot.load_extension('bot.cogs.owner')


async def main():
    await load_extensions()
    await bot.start(env.TOKEN)

if __name__ == '__main__':
    asyncio.get_event_loop().run_until_complete(main())

This is my __init__.py file for the cogs (setup):

intents = discord.Intents.default()
bot = Bot(owner_id=env.owner_id, command_prefix='.', intents=intents)


async def setup(bot):
    """
    Init bot's cogs
    """
    await bot.add_cog(Commands(bot))
    await bot.add_cog(Owner(bot))

This is the traceback when running __main__.py:

Traceback (most recent call last):
  File "D:/GitHub/Mamey_bot/bot/__main__.py", line 83, in <module>
    asyncio.get_event_loop().run_until_complete(main())
  File "C:\Program Files\Python38\lib\asyncio\base_events.py", line 616, in run_until_complete
    return future.result()
  File "D:/GitHub/Mamey_bot/bot/__main__.py", line 62, in main
    await load_extensions()
  File "D:/GitHub/Mamey_bot/bot/__main__.py", line 57, in load_extensions
    await bot.load_extension('bot.cogs.commands')
TypeError: object NoneType can't be used in 'await' expression

If I rewrite main() in __main__.py like in the first article:

async def main():
    async with bot:
        await load_extensions()
        await bot.start(env.TOKEN)

I would get a different traceback:

Traceback (most recent call last):
  File "D:/GitHub/Mamey_bot/bot/__main__.py", line 84, in <module>
    asyncio.get_event_loop().run_until_complete(main())
  File "C:\Program Files\Python38\lib\asyncio\base_events.py", line 616, in run_until_complete
    return future.result()
  File "D:/GitHub/Mamey_bot/bot/__main__.py", line 62, in main
    async with bot:
AttributeError: __aexit__

How can I fix this?

If I don't use asynchronous functions when running the bot in the container, the bot will get online, but the commands wont work.

CodePudding user response：

The issue was that my Dockerfile was installing the wrong discord.py version.

Inside the container

In the docker container RUN python3 -m pip install -U discord.py was installing Discord.py 2.0.1, and that's why the traceback was giving me "load_extension was never awaited" since I was using a deprecated syntax of 1.7.3.

After using the proper command in the Dockerfile: RUN python3 -m pip install discord.py==1.7.3 the issue disappears and the bot and its commands works perfectly.

On my real PC and the refactored code

My real PC/OS (outside the docker container) had the inverse issue: It had installed discord.py 1.7.3 and the refactored code was using discord.py 2.0.1 syntax. After running in the CMD py -3 -m pip install -U py-cord the refactored code that I shared in the original question works perfectly.

tl;dr: Need to be more careful on what versions I'm importing.
