Some playlists shows 0 videos even though they're not empty

[rramiachraf]

Describe the bug
As the titles suggests, when I visit some playlists they don't show any videos but when I try to view it on YouTube I can then access videos from the playlist.

Steps to Reproduce

1. Go to any Invidious instance.
2. Visit this playlist for example /playlist?list=PL8dPuuaLjXtNCG9Vq7vdvJytS-F-xGi7_.
3. You'll notice that It contains 0 videos.
4. Click on View playlist on YouTube.
5. Dozens of videos going to appear.

It could be because those videos are geo-restricted.
Try to use an invidious instance located in another country: https://instances.invidious.io

Duplicate of #92 then? Safe to close?

Not sure. I've tried many different instances (yewtube, kavin's 3 instances, snopyta) and none show the playlist videos. I'm waiting on their reply.

Not sure about that since I've tried every single public listed instance.

Ok, so there is an issue somewhere else! Thanks for your report :)

Update: Since the playlist is not blocked on my country, I tried the docker container on my local machine and It's showing 0 videos too, so the Geo-restriction is not an issue here at all.

Ok, so it's not related to geo-restriction at all.

It's just that those playlists are of a special kind: so called "learning playlists". And for those, youtube doesn't provide the number of videos (even though it's provided in search resullts and some other places).

Great work, you're absolutely right.
All the playlists which invidious shows 0 videos has a Learning playlist tag.

I think this may be resolved now
