My Question or Issue:

Hey!

Whilst developing some personal automation to sort a playlist, I've found several empty tracks in one of them.

To replicate perform the following equivalent request in Postman or Curl:

https://developer.spotify.com/console/get-playlist-tracks/?playlist_id=0nDLk7zdM3kPvyxpdUe3yL&market... 

If you do the above request from the Spotify developer pages, the track is not null... So I presume somethings gone amiss, but wanted to raise here.

Example response;

I have this when I select "Liked Songs" and then go to the playlist. 

It shows many empty songs with NaN play time. 

I have attached a screenshot.

I have this exact same problem with my Liked Songs list.

I get the same null result through the developer console.

If I replicate that correctly in the developer console (track offset 183, not 170) I see the same there as you have posted. So it is consistent. But I see no reason for that junk response, it seems malformed and that is Spotify's bug. I guess you just have to program defensively and ignore the track if it's null (similar to what you usually must do for local tracks).
