Unable to reproduce. What did you define your bot variable as? Can you also show your imports, please?

    def get_channel_on_guild(self, channel_name):
        channel_guild = discord.utils.get(self.get_all_channels(), name=channel_name).guild
        channel_id = discord.utils.get(self.get_all_channels(), name=channel_name).id

I should also mention that I'm on the master branch.

yeah same. regardless of what kind of bot definition I use (discord.Bot and commands.Bot) I still get the warning that it's not callable, tho when ran it works

This is also an issue for user_command, message_command.

So I've been really trying to see what causes this issue exactly and after looking in the code a bit and trying to understand it, I came to the conclusion that this warning was caused by the return type hinting of slash_command in bot.py, as upon removal of the type hinting for the return type, the warning went away.

This should have been fixed.
