Description

[Revised by @dirkf]
OP actually reported the bug for yt-dlp.

The problem, which was revealed by a change in the metadata served by YouTube, applied to both youtube-dl and yt-dlp and has been fixed in both programs.

There is a release of yt-dlp that includes the fix. See #31535 for discussion of whether this would be a good choice for you.

See below for ways to update to a fixed version of youtube-dl. Using -U doesn't (yet) work. A new release may be created, including the final fix, some time later than now. However, there is now a nightly build from the latest code here.

There's no point posting your log that shows the error now: feel free to thumb-up this post. Also, be aware that the initial patch still flagged the original issue as a WARNING; the fully fixed yt-dl doesn't. Consider raising a separate issue if your fixed yt-dl shows a different error.

I'm having the same issue here. Using youtube-dl version 2021.12.17

It seems that youtube might have changed something internally.

It seems to be some sort of regional(?) A/B-testing. I wasn't able to reproduce the issue at first either, but I was able to confirm the change in site behavior through affected users' page dumps. Youtube has begun serving web JSON where the ownerProfileUrl value is the @handle URL format instead of /channel/ or /user/, and this breaks the fatal _search_regex() used to extract uploader_id

In any case the extraction of an optional field shouldn't crash the extraction:

-            'uploader_id': self._search_regex(r'/(?:channel|user)/([^/?&#]+)', owner_profile_url, 'uploader id') if owner_profile_url else None,
+            'uploader_id': self._search_regex(r'/(?:channel|user)/([^/?&#]+)', owner_profile_url, 'uploader id', fatal=False) if owner_profile_url else None,

[Update] To quote @nicolaasjan:

That's not the real fix.
It was fixed with the merging of pull request #31675 two weeks ago.

Exactly. Don't apply this change. Use the suggested methods as linked from the Description, which you should read again if you were thinking of applying this change.
