I managed to make it work by adding images to the playlists that didn't have one (I had a couple of very old - 2008 - empty playlists without pictures).

[Brynyard]

Any tricks to lure rspotify or ncspot to dump information about which if my 200+ playlists suddenly lack information without having to rewrite the code yourself?

[OtaK]

@Brynyard Nope. I just went through a similar number of them myself. It's pretty easy to spot anyway. Just go on the web interface, any playlist with no picture at all (the autogenerated ones are OK) is a culprit.

[Brynyard]

@OtaK No luck, gone through all my playlists and checked that they both have songs and an image.

Reading the original bug report in rspotify it is clear that there's a major SW architecture issue (and they don't even want to touch it - it's not failing on the devs setup), so it seems I'll be best of just adding a patch dumping the offending JSON and work around this issue.

@Brynyard : use ncspot --debug tmp.log and fetch a recent/valid Bearer token:

[2024-03-28][09:02:33] [rspotify_http::ureq]
  [INFO] Making request Request(GET https://api.spotify.com/v1/me/,
  [authorization: Bearer <THIS_TOKEN_HERE>])

Then curl the json yourself:

curl 'https://api.spotify.com/v1/me/playlists?limit=50&offset=0' \
  -H 'Authorization: Bearer <THIS_TOKEN_HERE>' 
  -o playlist.json

Then use the error (also in the debug log):

[ureq::unit] [DEBUG] response 200 to GET https://api.spotify.com/v1/me/playlists?offset=0&limit=50
...
[ERROR] unhandled api error: json parse error: invalid type: null, expected a sequence at line 1 column 3764

And look over there in playlist.json. I suspect it was this before editing:

...,"images":null,"name":"Soft Trance",...
                ^- 3764

After:

...,"images":[{"height":null,"url":"https://image-cdn-fa.spotifycdn.com/image/ab67706c0000da849b6028390071f2d6c163da0a","width":null}],"name":"Soft Trance",...

@wdoekes just adding a track didn't work, I had to explicitly upload an image to some of the playlists for this to go away.

I had to explicitly upload an image to some of the playlists for this to go away.

Nobody said anything about adding tracks. The fix was to add an image.

[Brynyard]

Nobody said anything about adding tracks. The fix was to add an image.

I read it as "playlist is missing image, make sure it has one", and the playlists in questions didn't have an image and got one (auto generated) when I added a track that I was sure was available. Apologies for not fully comprehending all the nuances of this quirk.

[AndydeCleyre]

I tried the curl in @wdoekes message, but my entire playlist.json is:

{"href":"https://api.spotify.com/v1/users/andydecleyre/playlists?offset=0&limit=50","limit":50,"next":null,"offset":0,"previous":null,"total":0,"items":[]}

[AndydeCleyre]

Well after a few relaunches ncspot told me to log in again, with something like "bytes were left on the stream," and after logging in again the playlists loaded.

[neolight1010]

I'm experiencing this issue too.

[SebastianErfort]

My playlists weren't loading, but adding an image to a playlist without one fixed it for me. Thank you

[HappyGoFishing]

I have added images and it still doesnt load.

(EDIT) deleting my liked songs playlist fixed this.

Thanks for this advice. I had the same issue, I made sure there were images in every playlist and then the issue resolved.

A new version of rspotify was released. I updated the one in main branch yesterday. Does it fix your problems?
