Unable to load playlist or search for a track

[dsylla]

Hello,

I'm having an issue during the connexion process

M-x spotify-my-playlist
M-x spotify-search-track
M-x spotify-select-playlist

I'm on MacOS Big Sur 11.1 with GNU Emacs 27.1

my config.el

(setq debug-on-error 1)
(add-load-path! "private/spotify-dot-el")
(require 'spotify)
(setq spotify-oauth2-client-id "********************"
      spotify-oauth2-client-secret "*****************")
(setq spotify-transport 'connect)
(define-key spotify-mode-map (kbd "C-c .") 'spotify-command-map)

This is the output I get after a while in *Backtrace*

Unfortunately I don't have access to a similar hardware and OS in order to debug this. Other people who do might be able to help.

[elken]

I'm having the same behaviour on Linux except I'm not getting a *Backtrace* it just silently fails. I can access my playlists fine so there's no auth issue.

EDIT: with debug-on-error on I also get a failure relating to /me/player/devices

EDIT 2: Managed to capture output from *URL-DEBUG* https://gist.github.com/elken/4df5a2dc38506ed0c2da7318018821e7

EDIT 3: It actually seems to fail on Spotify's end too :/ https://developer.spotify.com/console/get-user-player/ fails for me with an unfulfilled promise

EDIT 4: Issue located, if there is no applicable device to play music on, /me/player returns a 204 which should probably be handled

Yes @elken I think the *Backtrace* buffer is from my "distribution" of Emacs (Doom Emacs).

Maybe the issue is not only from the package itself ... I'm not that good in Elisp so I'm not sure but from your output it seems like a there is also an issue with SSL ?

[dsylla]

UPDATE: I'm now able to load my playlists and a specific playlist but when I try to play a song nothing appends, and this time no error or trace whatsoever.

Nothing changed on my computer since my initial report. This leads me to think that maybe the issue is with Spotify API itself ...

[elken]

You have to have at least 1 device with Spotify open/able to stream to

Hi @dsylla -

I was getting this issue as well and have found some issues with Emacs' http request libraries. I've got a pull request submitted that uses request.el instead and it's behaving well. Maybe keep an eye on that and/or test it out?

[jkdufair]

@dsylla with the last PR merge, this issue should be resolved
