Description

I have aboslutely no idea of programming or anything alike. I am a paying Patreon to a user and I would like to download Audio shared by that Creator. If I copy the URL into Youtube-dl, it says "An extractor error has occurred. (caused by KeyError('post_file',))"
I have seen previous answers such as "try to use cookies" but I do not understand what to do with that answer. Is there a way to download Patreon Audios? And if so, what am I doing wrong?
