I can confirm that the following error is printed with Godot version v4.2.dev3.official.013e8e3af when right-pressing the button from the attached zip minimal reproduction project:

ERROR: Error calling from signal 'right_button_click' to callable: 'Control(Button.gd)::_on_my_color_picker_right_pressed': Method expected 0 arguments, but called with 0.

Your emit() does not provide the required argument.
But yeah, the error is strange.
