        return prefixes[str(message.guild.id)]

error is - Traceback (most recent call last): File "c:\Users\PC\OneDrive\Documents\3mbot\main code\mbot.py", line 71, in def on_guild_join(client, message): File "C:\Users\PC\AppData\Local\Programs\Python\Python39\lib\site-packages\discord\client.py", line 1002, in event raise TypeError('event registered must be a coroutine function') TypeError: event registered must be a coroutine function

I'm using python 3.9.0 with the latest pip. and latest discord.py github.

async def on_guild_join

not

def on_guild_join

TypeError: event registered must be a coroutine function discord.py
