Invalid get index 'controls' (on base: 'Node (')


There is an error in the godot editor that also appears in the official project source code ("Chapter 2 - Slow motion aiming").

The full error is the following:

res://src/Player/Camera/ - Invalid get index 'controls' (on base: 'Node (').
It seems to come from the "tool" keyword at the beginning of, but I don't know what is the problem.

    It's a strange error. You can ignore it I think - it doesn't affect the game's behavior.

    Now, if you want to remove it, you can add this code at the start of the ShakingCamera.reset_smoothing_speed() function:

    func reset_smoothing_speed() -> void:
    if Engine.editor_hint:

    The editor_hint property tells you if code is running in the context of the editor, allowing you to run some code only in the editor or only at runtime. Which we sometimes need for tool scripts.

    Note I'm saying it's a strange error because I don't see why the function runs at all. This error may have started appearing with a recent Godot version - I don't remember seeing it back when making the course (was with Godot 3.1 I think).
