Spotify links yield no data on loadtracks

[michihupf]

Hi

I am facing an issue where spotify urls aren't giving me any data, see logs below.
Queueing the song by just providing the song title and artist as a search query (and letting lavalink do its magic) it finds it on YouTube and plays it completely fine. As far as I understand lavasrc does this exact thing but gets the title and artist by way of the spotify API. Somehow this results in no matches thought. Is there anything I am missing?

For context. I am using lavalink-rs to make a private discord music bot. YouTube and SoundCloud already work but Spotify is giving me some issues.
