Shairport-server Response Code: 500 to Pipewire sends "POST /feedback RTSP/1.0"

[alexbramford]

• PipeWire version: 0.3.81
• Distribution and distribution version: "Fedora Linux 38 (Workstation Edition)"
• Desktop Environment: KDE 5.110.0 / Plasma 5.27.8
• Kernel version: 6.5.5-200.fc38.x86_64

Description of Question:

Why does Shairport respond with "Response Code: 500" when Pipewire sends POST /feedback to raop-sink?

1. Pipewire sends POST /feedback RTSP/1.0" to the Shairport-server
2. Shairport responds with Response Code: 500
3. Pipewire reports status: RTSP/1.0 500 Internal Server Error

How Reproducible:

Always

Steps to Reproduce:

Restart client and server, play music

1. Server side (Shairport-sync): sudo systemctl restart shairport-sync; systemctl status shairport-sync
2. Client side (F38): killall easyeffects; systemctl --user daemon-reload; sleep 1; PIPEWIRE_DEBUG=0 systemctl --user restart pipewire pipewire-pulse wireplumber
3. Play music
4. journalctl -f (client and server)

Thanks for the interesting port, but this is really a troubleshooting issue and could use some more information from the Shairport Sync end of things...

I've just posted it as an issue.
