cannot change a scene to packedscene

I wonder if, by calling deferred on the tree rather than the object the script is attached to, there's a gap where the stringified function name can't be traced back to a function.

Is there a way to do call_deferred("get_tree.change_scene_to_packed", MAIN_MENU)?

the resource doesnt have valid path for some reason

func _ready() -> void:
    //# prints ""
    print(MAIN_MENU.resource_path)

Having the same problem here, putting 'load' instead did fix it but every button doesn't work
