GStreamer fails to connect

[alazyworkaholic]

I just installed mopidy-spotify. ncmpcpp connects to mopidy-mpd and displays a list of tracks from my spotify playlists but it won't play any tracks. Raspbery Pi OS (Debian Bookworm) on R Pi 3B+ arm64 with wayland. Mopidy 3.4.2
Logs show lots of mopidy[75215]: ERROR [MainThread] mopidy.audio.gst GStreamer error: Failed to connect:

I also seem to have mpris problems.

Please let me know what other information would help fix this.

#Installation & Confguration

sudo wget -q -O /etc/apt/sources.list.d/mopidy.list https://apt.mopidy.com/bookworm.list
sudo apt update
sudo apt install mopidy mopidy-mpd mopidy-mpris

#Install gst-plugins-spotify
wget https://github.com/kingosticks/gst-plugins-rs-build/releases/download/gst-plugin-spotify_0.12.2-1/gst-plugin-spotify_0.12.2-1_arm64.deb
sudo dpkg -i gst-plugin-spotify_0.12.2-1_arm64.deb

#Install mopidy-spotify (brand new alpha, check upon next install)
sudo python3 -m pip install --break-system-packages Mopidy-Spotify==5.0.0a1

#Allow mopidy to send audio to pulseaudio
#Add the following under the ### Network access section of /etc/pulse/default.pa
load-module module-native-protocol-tcp auth-ip-acl=127.0.0.1

#Add to mopidy.conf under [audio]: output = pulsesink server=127.0.0.1

#Run as a service
#mopidy service runs under mopidy user, which is created upon pgk install
#Note that mopidy user must have access to any local music mopidy should play
#mopidy also needs access to your mopidy.conf, unless you want to copy everything into the system-wide default.
#A better idea is to grant mopidy access to the file and hardlink to it from a place it's looking for configs anyway.
#Note this won't work if /home is on a separate filesystem.

Did you ever resolve this? The config looks good, I am not sure what's going on. It's a general Mopidy issue rather than anything specific to this extension. You might get better help at https://discourse.mopidy.com/
