I'm trying to download facebook stories with youtube-dl. but it's returns unsupported url error.
I gone through many issues and articles but couldn't figure it out.
Firstly it gives error of invalid url error. i.e
https://www.facebook.com/login.php?next=https%3A%2F%2Fwww.facebook.com%2Fstories%2F166832464814864%2FUzpfSVNDOjY3OTEyMjQxNjg4NDgzMA%3D%3D%2F%3Fbucket_count%3D9&_fb_noscript=1

but this issue is resolved by adding cookies in command. it fixed but now issue changed.
I tried simple facebook videos with this package and it's working. facebook reels are also downloading but unfortunately it does not downloading.

any help would be appreciated.

here is my command.

**youtube-dl  --cookies ./cookies.txt  --verbose 'https://www.facebook.com/stories/166832464814864/UzpfSVNDOjU4MDM4NzUyNDE3MjM0Mw==/?bucket_count=9'**
