How do you properly set moving target to navigate to?

Question

I am trying to create an AI that follows the player. Right now I am coming across an issue that is_navigation_finished is returning true even though a new set_target_position has been set. The debug view shows that once the new target is set a line to show the path is not being created. So somehow the target being set I’m guessing is invalid or there is a race condition.

According to the documentation set_target_position should at least add another path to navigate towards

If set, a new navigation path from the current agent position to the target_position is requested from the NavigationServer.

Here is the code for the enemy:

extends CharacterBody3D
var movement_speed: float = 2.0
var movement_target_position: Vector3 = Vector3(0.0,2.26,4.65)

@onready var navigation_agent: NavigationAgent3D = $NavigationAgent3D
var mapRID : RID
@onready var bt :BTPlayer = $BTPlayer
func _ready():
	# These values need to be adjusted for the actor's speed
	# and the navigation layout.
	navigation_agent.path_desired_distance = 0.5
	navigation_agent.target_desired_distance = 0.5
	bt.blackboard.set_var(&"target", self)
	# Make sure to not await during _ready.
	actor_setup.call_deferred()

func actor_setup():
	# Wait for the first physics frame so the NavigationServer can sync.
	await get_tree().physics_frame
	
	mapRID = navigation_agent.get_navigation_map()
	
	# only is able to move when I call it inside here
	#set_movement_target(movement_target_position)

func set_movement_target(movement_target: Vector3):
	navigation_agent.set_target_position(movement_target)

func _physics_process(delta):
	if navigation_agent.is_navigation_finished():
		print("we are done")
		return
	var current_agent_position: Vector3 = global_position
	var next_path_position: Vector3 = navigation_agent.get_next_path_position()

	velocity = current_agent_position.direction_to(next_path_position) * movement_speed
	move_and_slide()

I am setting the new target every 10 secs on the enemy’s state machine like this:

func _tick(delta: float) -> Status:
	var target := blackboard.get_var(target_var) as Node3D
	if not is_instance_valid(target):
		return FAILURE
	print("new target set!")
	agent.set_movement_target(target.position)
	return SUCCESS

What is the correct way to change the target?

I feel really dumb. I set the target to itself so that it was always trying to move to its own position.
