The music playback queue for the discord bot is not working, what should I do?

Question

Python

I tried to figure out how to implement a playback queue, but I hit a dead end, and as I understand it, I wrote nonsense. I would be glad for any help:>

If this is the most stupid mistake, then please don't hate, I'm just learning.

Here is the error, it does not always appear and the queue still does not work, but the music is played.

Answer 1

vc.play(source, after = toggle_next)
await songs.put(vc.play)
You start playback by calling the vc.play() method, and then queue a reference to this method.
What do you think it should do? Because it obviously doesn't, and won't.
