Hello, people. This happens to me when I'm moving a playlist from Spotify to Youtube Music. Is there any solution?

It's probably a problem with the way you set up your credentials. Which setup method did you use? Can you check your settings.ini file?

Use the method as instructed in the Github
First I made the Spotify dashboard. The redirect link is the one from http://localhost. And then I did the authorization by Google OAuth. Although I don't know if that is created automatically or where it is created?

[sigma67]

If you did everything correctly it should probably work. To troubleshoot you need to manually inspect the settings.ini file, which is created automatically.

It should be in platformdirs.user_cache_dir/spotify_to_ytmusic, depends on your platform where that is

I am having the same issue as djlivooo
To be fair the playlist has 1002 tracks in it, another playlist transfered fine before I tried the large playlist
I tried to transfer the larger one a second time and it worked.

Anyway I tried to find the settings.ini file you mentioned, I could find the example ini file but not the ehm "real" one?
I use scoop to install applications and used it to install python so it seems it saves installed python packages in its folder structure.

@Lod3 the settings file should be in %APPDATA%/spotify_to_ytmusic

I'm consistently seeing this with trying to import https://open.spotify.com/playlist/3YgiYNSYXeKWPkcVKZY4xc - it is a rather large playlist with thousands of entries, so that seems to match with the original report. I've successfully imported a far smaller one, so I believe my config should be right. I've not yet had the time to investigate further than this, but I thought I'd provide what is (to me) a consistent reproduction of these symptoms.

[sigma67]

Maybe the issue is that too many videos are being passed to create_playlist.

YouTube's playlist limit is at 5000: https://webapps.stackexchange.com/questions/77790/what-is-the-maximum-youtube-playlist-length

so it is in fact impossible to transfer this playlist. Could implement an exception for this case

Ah, I was wondering if there was some kind of API limit, I hadn't considered that there would just be a playlist size limit, thanks
