Original GitHub issue: https://github.com/aome510/spotify-player/issues/398

The column to show playlists don't show up on the homepage

The backtrace is empty but the log gives me the following line:

2024-03-22T15:14:54.980917Z ERROR client_request{request=GetUserPlaylists}: spotify_player::client::handlers: Failed to handle client request: invalid type: null, expected u32 at line 1 column 7147

I found out which part of the returned json by the GetUserPlaylist request was problematic by looking up the column number and see what the problem was, I got this response by setting RUST_LOG=DEBUG and getting the log statement before the ERROR log.
This is the problematic part of the json where the "total" key in the returned "tracks" object is null, this makes spotify-player not show any playlists. all the other "total" keys of my playlists are a number on the other hand.

      {
         "collaborative":false,
         "description":"We made you a personalized playlist with songs to take you back in time.",
         "external_urls":{
            "spotify":"https://open.spotify.com/playlist/37i9dQZF1EuyeQlxxtnSue"
         },
         "href":"https://api.spotify.com/v1/playlists/37i9dQZF1EuyeQlxxtnSue",
         "id":"37i9dQZF1EuyeQlxxtnSue",
         "images":[
            {
               "height":null,
               "url":"https://daily-mix.scdn.co/covers/time-capsule/time-capsule-blue_DEFAULT-en.jpg",
               "width":null
            }
         ],
         "name":"Your Time Capsule",
         "owner":{
            "display_name":"Spotify",
            "external_urls":{
               "spotify":"https://open.spotify.com/user/spotify"
            },
            "href":"https://api.spotify.com/v1/users/spotify",
            "id":"spotify",
            "type":"user",
            "uri":"spotify:user:spotify"
         },
         "primary_color":"#ffffff",
         "public":true,
         "snapshot_id":"MTcxMTA2NTYwMCwwMDAwMDAwMDdkOTNiNDljY2RiNjgyNTM5MDA2YzE5OTcwZDQ3NmI1",
         "tracks":{
            "href":"https://api.spotify.com/v1/playlists/37i9dQZF1EuyeQlxxtnSue/tracks",
            "total":null
         },
         "type":"playlist",
         "uri":"spotify:playlist:37i9dQZF1EuyeQlxxtnSue"
      },

Seems like this is one of those special playlists made by spotify that somehow has a total of null tracks inside (maybe I didn't open the playlist yet)

So I just opened and closed this playlist on my phone's spotify app, and the total doesn't seem to get updated though unfortunately, I still get the same error.

ahhh, another Spotify API type bug again. I can implement patch to workaround this issue. I do hope that Spotify makes their official API more "stable" sigh.

It seems that this playlist belongs to Spotify. Can you try to remove and add the playlist back to your library again?

Yeah that seems to have fixed the issue, now it correctly recognizes how many total tracks there are in this playlist and the issue doesn't show up again. weird how spotify reports null for the total before though.

Great to hear that it fixes the issue. Spotify API is a bit inconsistent. We recently encountered a few issues (https://github.com/ramsayleung/rspotify/issues/452) with their APIs.

I'll close this issue for now.

Before the next release, one may use the API to check which playlist is the culprit. Go the the spotify API documentation link below and test the query with limit = 50 offset = 0 on your own account (you need to be logged in):
https://developer.spotify.com/documentation/web-api/reference/get-a-list-of-current-users-playlists
Then Ctrl+F for "total": null is similar
