[wireplumber] waybar exits when wireplumber/pipewire configuration is corrupted/inconsistent #4584
Description
This looks like a bug in wireplumber plugin that doesn't handle invalid configuration gracefully. More generally I think even if the plugin fails to initialize it should not crash the whole waybar application.
config:
"wireplumber": {
"format": "{volume}% {icon}",
"format-muted": "",
"on-click": "helvum",
"format-icons": ["", "", ""],
},
"wireplumber#source": {
"node-type": "Audio/Source",
"format": "{volume}% ",
"format-muted": "",
"on-click": "wpctl set-mute @DEFAULT_AUDIO_SOURCE@ toggle",
"scroll-step": 5,
}

Note that the default audio/source doesn't exist. I had to switch audio card profile (wpctl set-profile 45 3) in order to play sound via speaker connected to the monitor (LG HDR 4K) and this made the config invalid.
