  22 février 2023, par kris

  Everytime I try to run play command in my bot, I get this error in the terminal, kind of new to coding so not exactly sure whats going on. It was working just fine, then it started not to work.

  this is my music_cogs.py, this is where error is coming from

  


  was working just fine then it started to give me this error after a while.

  


  raceback (most recent call last):
  File "C:\Users\poopt\AppData\Local\Programs\Python\Python38\lib\site-packages\discord\ext\commands\core.py", line 229, in wrapped
    ret = await coro(*args, **kwargs)

  File "c:\Users\poopt\Code\cool_bot\cogs\music_cog.py", line 44, in play_music
    m_url=self.music_queue[0][0]['source']
KeyError: 'source'

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