[introspection3]

notify {"error": "beeep: The name org.freedesktop.Notifications was not provided by any .service files; exec: "kdialog": executable file not found in $PATH"}

Not related to OS or RPi, you are missing some notification-daemon (any will do), notify-send, or kdialog, it will first try with the dbus method and will fall back to alternatives and you are missing all of that.
