Description

The YT page that channel videos are extracted from has changed its layout, and this is causing parseChannelVideoResponse to not return any videos. Also, the community tab isn't always the 4th tab anymore, and this can cause errors. This PR aims to fix these things by updating the way that page is parsed.

Additional context

I assume this layout change was A-B tested because these issues occurred sporadically until recently.

Some users in the freetube matrix channel had discussed how they were able to change their backend preference to Invidious in order to solve this issue, but it seems that this issue is also effecting Invidious now (EX: https://invidious.namazso.eu/channel/UCXuqSBlHAE6Xw-yeJA0Tunw doesn't display any videos).

I ran the automated tests, and the only issue I ran into was with shorts missing their lengthSeconds. It doesn't seem like the reelItemRenderer displays the length of the video, so I am unsure what to do about this:

Could you please fix the linting issues and take a look at the failing test?

[PrestonN]

I was notified that the one failing test is okay for this PR because that channel in particular doesn't have a videos tab any more due to the changes made to the site, so it should be okay to go ahead and merge this.

Thank you very much for the fix!

I actually had a fix for something I was about to push. It's okay. I can make another PR. The channelName and channelId moved inside of channel continuations, and it means that getChannelVideosMore throws.

Hi there, could someone explain to me how to apply these fixes?? I just made an account to ask cause I'm having this same problem as well; it's the local API error that says "TypeError: cannot read properties of undefined (reading contents)" and no videos showing up when viewing a channel page, I'm using the portable version of Freetube, beta version 0.17.1, and local API/default settings on general settings. I apologize if this is the wrong place to post, but I'd really appreciate if someone could help.

Ok then thanks, I didn't know if an update was close to being released soon or not, would have used this workaround if I knew how to apply it.

Or you can download latest nightly (use at your own risk) version at https://github.com/FreeTubeApp/FreeTube/actions/workflows/build.yml

Backup data before using it (I backup data on every new subscription made anyway)

I might just give that a try; I'm currently using the stable portable version of FT, so maybe I'll try installing the nightly exe version and see if that helps. Thanks. :)

[SJRouge91]

Oh wow, so I just finished installing the nightly beta 0.18.0 version, and the videos show up on the channels now! I'll probably just go ahead and use the beta version in the meantime. Thanks again for the rec to use the nightly one :) @PikachuEXE
