Ubuntu 22.04: Gdk-CRITICAL **... gdk_wayland_window_set_dbus_properties_libgtk_only: assertion 'GDK_IS_WAYLAND_WINDOW (window)' failed

I encountered this error when running the soffice commandline interface under Jammy Jellyfish (Ubuntu 22.04). Since there wasn't any window being generated I was puzzled. A little searching revealed that the library libgdk3.0-cil (CLI binding for GDK 3) was not installed, and so running:

sudo apt install libgdk3.0-cil

solved the problem.
