Spotify playlist - title and cover art problems again?

[TommyTaif]

Hi there,

I just finished building my jukebox. So thanks a lot to the community for making this amazing project possible.
I installed version 2.8.0 about three weeks ago (Pi Zero 2) tried it a bit and everything worked fine, including Spotify playlists.
After finishing the hardware today I noticed that new Spotify playlists no longer show the cover art nor the title in the web app. The files in the playlist folders are present, but empty. The only thin I did in the meantime was installing the Pimoroni ONOffShim scripts. That doesn't sound like it should have anything to do with that. the three week old entries still work fine.
I saw that there were similar problem two to three years ago, which were fixed back then. Is anybody seeing the same? Any advice?

Cheers,
TommyT

It looks like inc.viewFolderTree.php has a problem for me. It reads the stream address in line 117:
$uri = file_get_contents($subfolder."/spotify.txt");

But spotify.txt contains the address in a format like
spotify:album:4wjxmqXnSQvBZWL3IbYngX

The next line generating the URL seems to need
https%3A%2F%2Fopen.spotify.com%2Falbum%2F4wjxmqXnSQvBZWL3IbYngX

Not knowing much about php, I replaced line 118 with

$urisegments = explode(":", trim($uri));
$url = "https://open.spotify.com/oembed?url=https%3A%2F%2Fopen.spotify.com%2F".$urisegments[1]."%2F".$urisegments[2]."&format=json";

This works now fine (tested for albums and individual songs). I cannot understand why it was working fine the way it was two weeks ago. Did Spotify change their API?

Anyway, I will mark my question as answered, but leave it here for reference.

Cheers,
TommyT
