Original GitHub issue: https://github.com/librespot-org/librespot/issues/1438

Description

When I use the Spotify desktop application (Linux) to transfer playback to the librespot device, librespot fails to find a track
"ERROR librespot_connect::spirc] ContextError: Invalid state { track uri contains invalid characters }" and does not resume playback.

Version

v0.6.0-15-g7003e98

How to reproduce

  1. Launch librespot (without args)
  2. Start playing a song on Spotify desktop app
  3. Using the desktop app, transfer playback to the 'librespot' device

Originally created by @FabioGNR on GitHub (Jan 11, 2025). Original GitHub issue: https://github.com/librespot-org/librespot/issues/1438 ### Description When I use the Spotify desktop application (Linux) to transfer playback to the librespot device, librespot fails to find a track "ERROR librespot_connect::spirc] ContextError: Invalid state { track uri <None> contains invalid characters }" and does not resume playback. ### Version `v0.6.0-15-g7003e98` ### How to reproduce 1. Launch `librespot` (without args) 2. Start playing a song on Spotify desktop app 3. Using the desktop app, transfer playback to the 'librespot' device ### Log ``` [2025-01-11T19:28:49Z INFO librespot] librespot 0.6.0-dev 7003e98 (Built on 2025-01-11, Build ID: 0lU6IYBT, Profile: debug) [2025-01-11T19:28:49Z TRACE librespot] Command line argument(s): [2025-01-11T19:28:49Z TRACE librespot] R "100" [2025-01-11T19:28:49Z TRACE librespot] verbose [2025-01-11T19:28:49Z DEBUG librespot_core::session] new Session [2025-01-11T19:28:49Z DEBUG librespot_discovery::server] Zeroconf server listening on 0.0.0.0:43803 [2025-01-11T19:28:49Z INFO librespot_playback::mixer::softmixer] Mixing with softvol and volume control: Log(60.0) [2025-01-11T19:28:49Z DEBUG librespot_playback::player] new Player [0] [2025-01-11T19:28:49Z INFO librespot_playback::convert] Converting with ditherer: tpdf [2025-01-11T19:28:49Z INFO librespot_playback::audio_backend::rodio] Using Rodio sink with format S16 and cpal host: ALSA [2025-01-11T19:28:49Z INFO librespot_playback::audio_backend::rodio] Using audio device: default [2025-01-11T19:28:49Z DEBUG librespot_playback::audio_backend::rodio] Rodio sink was created [2025-01-11T19:28:53Z DEBUG librespot_discovery::server] POST "/" {} [2025-01-11T19:28:53Z DEBUG librespot_core::session] Shutdown: Invalidating session [2025-01-11T19:28:53Z DEBUG librespot::component] new MercuryManager [2025-01-11T19:28:53Z DEBUG librespot::component] new ChannelManager [2025-01-11T19:28:53Z DEBUG librespot_core::session] new Session [2025-01-11T19:28:53Z DEBUG librespot_playback::player] command=SetSession [2025-01-11T19:28:53Z DEBUG librespot_core::session] drop Session [2025-01-11T19:28:53Z DEBUG librespot_connect::spirc] new Spirc[0] [2025-01-11T19:28:53Z DEBUG librespot::component] drop ChannelManager [2025-01-11T19:28:53Z DEBUG librespot::component] drop MercuryManager [2025-01-11T19:28:53Z DEBUG librespot::component] new DealerManager [2025-01-11T19:28:53Z DEBUG librespot::component] new SpClient [2025-01-11T19:28:53Z DEBUG librespot_core::spclient] Client token unavailable or expired, requesting new token.

@FabioGNR commented on GitHub (Jan 11, 2025):

In the playback.current_track field of TransferState I only see uid filled in, uri is None.
I have not yet been able to find a reference to the track uri or index in the Liked Songs.
However, the metadata field of ContextTrack does have the correct title of the song.

I now see it should be able to get the track based on gid, but it appears because "uri" is an empty string instead of None, it does not reach that branch. I'll try to see if handling empty uri string fixes this.
