Copy all playlist fails: KeyError 'runs'

[notSoWiseOldMan]

I think there is some missing error handling or the api response from spotify was updated.

I've done some investigation into this and this looks like a bug in ytmusicapi and I'm not sure what the correct resolution there is. I've filed bug https://github.com/sigma67/ytmusicapi/issues/539 over there. I've also detected this error in s2ytmusic and displayed a message about it.

I'm afraid that until this bug gets fixed in ytmusicapi, you won't be able to use "copy_all_playlists", you'll need to manually copy the playlists by playlist ID (the bug is in the code that lists the playlists, and that's how I search for a playlist by name, without being able to search for playlist by name, my code will just end up creating new, possibly duplicate playlists every run.

I just tried adding a patch to ytmusicapi to print out debug information in the event of a traceback. Can you try a python -m pip install --upgrade spotify2ytmusic and run copy_all_playlists again, hopefully it'll give an error and hopefully we can debug the issue.

Thanks, Here is the output after updating that package. I will trying importing the Running playlist individually and see if it also chokes on that.

Attempting to look up playlist 'Running' failed with KeyError: 'runs'
This is a bug in ytmusicapi that prevents 'copy_all_playlists' from working.
You will need to manually copy playlists using s2yt_list_playlists and s2yt_copy_playlist
until this bug gets resolved.  Try `pip install --upgrade ytmusicapi` just to verify
you have the latest version of that library.

I get a similar error when trying to import individual playlists. I re-ran ytmusicapi oauth first to be sure my token hadn't expired.

Ok, I had an empty playlist that matched my youtube username. After deleting that playlist on youtube mustic both the individual playlist import and import all playlist functions worked. So I think there just needs to be a check somewhere when looking at the YT music playlist to handle if the playlist is empty.

IDK where that empty playlist came from. 2 things I can think of.

1. I was an old google play music user so it may have come from the transfer to YT music which I never used back then.
2. I am currently on a trial youtube premium account... maybe something about that created this playlist?

Anyway it is working for me now and I got all my music. Thank you for making this tool! I'll be using it to help my friends switch over!

I tried creating an empty playlist named after my username, and ran copy_playlist to "+Jazzy" and to my new empty playlist named after my userid, and neither one ended up triggering this, so there must have been something related to that playlist that was beyond just an empty playlist named after your username...
