Dear Maintainer, after upgrade to libhyprwire3 0.3.1-1 attempts to control
hyprpaper with "hyprctl hyprpaper" causes hyprctl to hang and use 100% CPU with
message:

    [hw] err: [3 @ 1.652] -> Generic message references unknown object 2

hyprpaper/unstable,now 0.8.3-1+b1
libhyprwire3/unstable,now 0.3.1-1

Works fine with libhyprwire3 0.3.0-3+b1
