Librespot crashes on some songs, this is 100% reproducible (pi musicbox and libreelec).
The song causing the crash is not working with chromecast either, so probably spotify doesn't allow to play this song externally. It would be nice if we could just skip this song instead of the assertion :-).

It would probably be helpful if you could give some track IDs causing this.

@michaelherger
How can I find these IDs as parsing fails?

In the Spotify applications there's a "..." menu item which allows you to copy the item's URI.

Something strange is going on here, spotify doesn't have URLs for the crashing songs.

"Delen" = "Share" and allows me to get the URL.

Normal song:

It looks like the song in the playlist is refering to a song on an album
that doesn't exists anymore on spotify

probably the spotify software searches for an alternative and librespot
doesn't.

that's my five cents anyway...

cheers

I hit the same, seems a lot like what you suggested.
Since librespot is not maintained anymore I suppose it's just tough luck :(

An example of a failing song would be helpful.

To reproduce, you can create a playlist on Spotify desktop, add a local directory and then add a local song to the playlist. When librespot then tries to play that song, this assertion will fail since it does not correspond to a song available on Spotify.

Since this issue has no backtrace, no sample songs to reproduce, and no further reports within the past couple of months, I'm closing this. Please reopen with a backtrace and sample songs if this error still occurs.
