Answer 1

The "callable" in the error message is "on_id_pressed", which doesn't exist.

Change:
popup.connect("id_pressed", self, "on_id_pressed")
to:
popup.connect("id_pressed", self, "_on_id_pressed")

Answer 5

You're trying to use Godot 3 code in Godot 4.

Change line 10 to:
popup.id_pressed.connect(_on_id_pressed)

In the future, please mention your Godot version when asking for help with a problem. There have been many changes between 3 and 4.
