How can I resolve the error 'str' object has no attribute 'is_paused' in discord.py?

Question

[2023-02-19 05:14:12] [ERROR ] discord.ext.commands.bot: Ignoring exception in command play Traceback (most recent call last): File "C:\Users\toto\AppData\Local\Programs\Python\Python310\lib\site-packages\discord\ext\commands\core.py", line 229, in wrapped ret = await coro(*args, **kwargs) File "C:\Users\toto\PycharmProjects\pythonProject\music_bot-main\main.py", line 101, in play elif self.is_paused: AttributeError: 'str' object has no attribute 'is_paused'

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

Answer 1

You've given lots of non-class methods the self parameter. So self ends up being your context object and ctx the command argument. Just remove self from the methods that don't need it. ie, every method that doesn't belong to a class.

async def play(ctx, *args):
    ...


async def pause(ctx, *args):
    ...


async def resume(ctx, *args):
    ...


async def skip(ctx):
    ...


async def queue(ctx):
    ...


async def clear(ctx):
    ...


async def dc(ctx):
    ...

Above are the ones that need changing.
