NavigationAgent2D doesn't return the right get_next_path_position()

Godot Version

v4.2.2

Question

get_next_path_position() always returns the enemy’s current position.
I’ve read some other posts and I understood this should be because I haven’t set a navigation layer on my tilemap but even after I added it, and painted the right tiles with it, the navigation agent still refuses to get the next position.

This is my code for navigation in the Enemy class:

var current_pos: Vector2 = global_position
	var next_pos: Vector2 = navig_agent.get_next_path_position()
	var new_velocity: Vector2 = current_pos.direction_to(next_pos) * speed
	
	if navig_agent.avoidance_enabled:
		navig_agent.set_velocity(new_velocity)
	else:
		_on_navigation_agent_2d_velocity_computed(new_velocity)

These are the settings on NavigationAgent2D and TileMap respectively:

I genuinely have no clue on why this doesn’t work yet
