unable to change scene after emit a signal

[monemagrafica]

Hi!, i don't know if is a bug or not.
But i have a dialog, something like

- Second one
	do emit("change_scene")
	Voice: You picked the second one.`

the "change_scene" is a global signal in global.gd

i catch the signal the dialog scene:

func goToScene():
	get_tree().change_scene_to_file("res://level/level.tscn")


func _ready():
	DialogueManager.show_dialogue_balloon(load("res://dialog/intro.dialogue"), "start")
	Global.connect("change_scene", goToScene)
	pass # Replace with function body.

it should change scene but everything is crashing with the message: "Invalid get index 'process_frame' (on base: 'null instance')."

what i'm doing wrong?
