MPRIS returns an empty array

[mtshrmn]

Description

This is a follow up to #503
In the issue, it is instructed to use your own Spotify client id when running spotifyd.

I've followed the instructions by creating a new id and setting the SPOTIFYD_CLIENT_ID environment variable.
however, the error still persists.

To Reproduce

run: SPOTIFY_CLIENT_ID=ID spotifyd --no-daemon
(in fish that's how you set the environment variable)

Expected behavior

should not show the error

The issue had a template for a reason. You didn't provide any log files or information about the system you are running.
Why do people ignore my templates... 🤦 It's like the first thing people do is to ctrl-a-delete the content 😔

You're right, I'm sorry, updating the issue.

I just tried to make add a set method to the volume property.
In doing so, I discovered more issues on the dbus, such as the one described here.

if I try:
dbus-send --session --print-reply --dest=org.mpris.MediaPlayer2.spotifyd /org/mpris/MediaPlayer2 org.freedesktop.DBus.Properties.Get string:'org.mpris.MediaPlayer2.Player' string:'Metadata'

I get:
method return time=1647187893.258206 sender=:1.1051 -> destination=:1.1052 serial=9 reply_serial=2 variant array [ ]

@eladyn stated here #1047 that this may be because of an expired token.

I think that this is another problem, but not the main one

Because even if the token is not expired, an empty array will be returned. This seems to be the case because the response from the Spotify API is in a different format from what Rspotify expects.

Rspotify has just added this "collection" variant:
ramsayleung/rspotify#306

However, the current release of Rspotify breaks compatibility with the currently used version.

This phenomenon btw also applies to the other methods with similar implementations - such as the volume property, which always returns the default value of 0.

BTW, this issue does not affect metadata which is fetched for the properties changed notifications because it used a different method.
instead of requesting information of the currently playing track, it uses the track_id provided by librespot PlayerEvent to fetch metadata for this particular track id.

It would be great if a new version of Rspotify would be implemented.

So rspotify is now on the newest version, can anyone confirm or deny that this problem does no longer occur?

[bartlibert]

For me it works fine now.

Thanks for the feedback, going to close this. If anyone runs into this problem again, feel free to reopen!
