[Godot 2.1.4] Ray cast from camera not working

I'm trying to cast a ray from the camera into 3D space, and I followed the examples from the docs, but it's not working for some reason. Shouldn't this work?

var ray_query_from
var ray_query_to
var mouse_pos
#
# (...)
#
func _input(event):
    if event.is_action_pressed("editor_select"):
        mouse_pos = get_viewport().get_mouse_pos()
        ray_query_from = camera.project_ray_origin(mouse_pos)
        ray_query_to = ray_query_from + camera.project_ray_normal(mouse_pos) * 1000
        set_fixed_process(true)
#
func _fixed_process(delta):
    var space_state = get_world().get_direct_space_state()
    var result = space_state.intersect_ray(ray_query_from, ray_query_to, [self])
    print("result: ", result)    #<--------   always comes out empty
    set_fixed_process(false)

I have several Areas with CollisionShapes set with BoxShapes that should be being hit but aren't. result dict is always empty.

    Nevermind. I double checked the intersect_ray() function and by default it's not set to collide specifically with Areas.
    Fixed by changing line 16 to:

    var result = space_state.intersect_ray(ray_query_from, ray_query_to, [self], 0xFFFFFF, space_state.TYPE_MASK_AREA)
