invalid get index 'hp' (on base: null instance) on line 24

sepiran

I'm following heartbeast moblie rpg and get invalid get index 'hp' (on base: null instance) on line 24 i don't understand why i'm using the the latest stable version of godot.

 extends Node2D

var hp = 25 setget set_hp

onready var hpLabel = $HPLabel
onready var animationplayer = $AnimationPlayer

signal died
 
func set_hp(new_hp):
	hp = new_hp
	hpLabel.text = str(hp) + "hp"
	
	if hp <= 0:
		emit_signal("died")
		queue_free()
	else: 
		animationplayer.play("Shake")
		yield(animationplayer, "animation_finished")
		animationplayer.play("Attack")
		yield(animationplayer, "animation_finished")
		var battle = get_tree().current_scene
		var player = battle.find_node("playerStats")
		24. player.hp -= 3

it seems battle.find_node("playerStats") does not find such a node. 1. Have you ensured it exists? 2. have you checked the docs regarding the additional parameters you can pass to find_node ?
