Invalid get Index 'position' (on Base: 'Nil')

Question

extends Area2D
var speed = 3
var move = Vector2(0,0)
var look_vec = Vector2(0,0)
var player = null

func ready():
lookvec = player.position - global_position

func physicsprocess(delta):
move = Vector2(0,0)

move = move.move_toward(look_vec, delta)
move = move.normalized() * speed
position += move

Answer 1

You have player = null on line 5, so player.position fails with the error message in the title.
