async init

[elfin rune]

a class __init__?

you don't.

OK?

Explain what you're trying to do and show code.

Then just do self.session = aiohttp.ClientSession(...)
and use that session in your async requests methods

[placid mason]

You don't create a session in init

[elfin rune]

Or you can do something more complex like:
https://github.com/onerandomusername/monty-python/blob/main/monty/bot.py#L95-L185

[placid mason]

You can pass it from outside

[elfin rune]

Or that ^

[placid mason]

async def main():
    async with aiohttp.ClientSession() as session:
        bot = ChatBot(..., session=session)
        ...
        await bot.run()

This ensures the session will be closed when the bot quits etc etc

How do you run your bot

Why is that relevant

Your problem is obtaining an async resource during initialization
How's what you posted relevant to the problem
