Невалиден установен индекс на годишния

невалиден набор от индекси на годишния

This will usually be because you set the wrong name to a variable 
or wrong data type. For example, I got this when I was following a tutorial
 and did "onready var sprite: Sprite =  get_node("Sprite"), which
 was right for the tutorial, but remember to use your own names 
 if you change them from a tutorial!
