Invalid Get Index: '1' on base: Array

Question

hi, can anyone help me?
I have a little problem, for some reason it throws an error when I try to use getsimplepath() in the generate_path() function. The path, for some reason, is not written to the array and gives an error when used in the navigate() function.

extends KinematicBody2D

export var mob_speed = 200
var velocity = Vector2()
var path : Array = []
var navigation : Navigation2D = null
var target = null

func _ready():
    navigation = get_tree().current_scene.get_node("Navigation")


func _physics_process(delta):
    initiate_target()
    generate_path()
    navigate()
    chase()

func initiate_target():
    if get_tree().current_scene.get_node_or_null("Player/HitBox") != null:
        target = get_tree().current_scene.get_node("Player/HitBox")
    else:
        target = null

func navigate():
    velocity = global_position.direction_to(path[1]) * mob_speed
    if position == path[0]:
            path.pop_front()

func generate_path():
    if navigation != null and target != null:
        path = navigation.get_simple_path(position, target.global_position, false)


func chase():
    velocity = move_and_slide(velocity)

You're removing entries from path, but you're not checking if there's none left.

BTW, according to the docs, getsimplepath is deprecated.

Thank you so much!
