a problem with my enemy script

I’ve been trying to run a navigation enemy with this script

extends CharacterBody3D

var player = null

const SPEED = 4.0

@export var player_path : NodePath

@onready var nav_agent = $NavigationAgent3D

func _ready():
player = get_node(player_path)

func _process(_delta):
velocity = Vector3.ZERO

nav_agent.set_target_position(player.global_transform.origin)
var next_nav_point = nav_agent.get_next_path_position()
velocity = (next_nav_point - global_transform.origin).normalized() * SPEED

look_at(Vector3(player.global_position.x, global_position.y, player.global_position.z), Vector3.UP)

move_and_slide()

and im getting an error for

player = get_node(player_path)

it says Invalid get index ‘global_transform’ (on base:‘null instance’) as an error

i’ve been using a tutorial and i don’t know how to fix it really, mainly cause i just started godot out 2 days ago, also i am a literal boomer with this type of stuff so any suggestions or alternate code i can use instead of this would be greatly appreciated

Thanks,

I am guessing the enemy is loaded before the player is ready, though it should give another error at _ready if that was true, something along the lines of “Couldn’t find node: /root/player”

Instead of exporting a path to the player, try exporting the player itself. If you have a class_name Player on the player script then use that type instead

@export var player: CharacterBody3D
