Description

On Facebook, I am unable to download a private video from a private group. Back in August, I was able to download another video from the same group with the same command (without --force-generic-extractor).

Video at hand: https://www.facebook.com/malika.dance/videos/10157074910391854/ (will not work for you obviously 😊)

When accessing this URL in the browser, I noticed that it would be transformed to https://www.facebook.com/groups/543850796513585/permalink/692330884998908/ but youtube-dl can't parse that because it's technically not a video (group feed).

Trying to redownload the video from August does not work. Using --force-generic-extractor (suggested in other issues) does not change the error.

Thank you!
