Pagination broke, thanks Google

[victorjzsun]

New bug related to pagination tracked at https://issuetracker.google.com/issues/196478069?pli=1. If you see an error message similar to API call to youtube.playlistItems.list failed with error: The request specifies an invalid page token., this is the reason

Will implement retry mechanism as a temporary solution asap

Thanks for highlighting the issue.

It's weird since the playlist ID quoted in the error matches the channel ID but with the channel's initial UC replaced by UU. I wonder if there is something in the code that can fix this? There is some playlist/user/channel validation taking place and if YouTube changed an API this may need updated?
Only guessing though since I haven't had time yet to test anything.

Doesn't seem to be effecting channels where I can list them by username instead of channel ID. Or where I have specific playlists IDs listed.

Not all channels have a 'username' - I believe the channel needs to reach a certain subscriber number before YouTube offers the owner the ability to have a plain text username. But where you can, it may be worth swapping any channel IDs for usernames.

For usernames, I still go through the uploads playlist (UU...) to get the videos so there's no difference there. If provided a username, I just add a step to get the channel ID from the username and then use that to get videos.

I was also able to get an error using a proper playlist ID (PL...) so it's not just a UU... playlist problem. I don't think this is an intended change, so will try to use a workaround for the time being and follow the API/issuetracker for progress
