When using pytube to download a YouTube video and discord.py to play it, I am getting a OSError: [Errno 9] Bad file descriptor error. I've had this working at one point and can't seem to figure out what I changed which broke it.
Full traceback:

I've mounted the /media/ dir during docker -v and can see the file is getting downloaded and when I copy the file to my local machine I can play it in an audio player.
The program can access the SQLite database right next to the files in question just fine.
I've deployed the container locally and to two different VPS's with the same file structure with the same behavior. I'm ripping my hair out.
