form is not activated in Rasa 2.0 - rasa-nlu

Question

I'm trying to integrate a form in my rasa chatbot.
In domain.yml, I have included the following:
I declared the slots:
slots:
question1:
type: text
question2:
type: text
question3:
type: text
the questions that the form is supposed to send to the user:
utter_ask_question1:
- text:" first question goes here"
utter_ask_question2:
- text:" second question goes here"
utter_ask_question3:
- text:" third question goes here"
defined the form as:
forms:
user_quiz_form:
question1:
- type: from_text
# entity: date
question2:
- type: from_text
question3:
- type: from_text
the actions section also contains :
actions:
- action_submit
- user_quiz_form
The file rules.yml contains:
- rule: Activate quiz form
steps:
- intent: quiz
- action: utter_quiz
- action: user_quiz_form
- active_loop: user_quiz_form
- rule: Submit quiz form
condition:
- active_loop: user_quiz_form
steps:
- action: user_quiz_form
- active_loop: null
- slot_was_set:
- requested_slot: null
- action: action_submit
and actions.py is:
from typing import Any, Text, Dict, List
from rasa_sdk import Action, Tracker
from rasa_sdk.events import SlotSet, EventType
from rasa_sdk.executor import CollectingDispatcher
import webbrowser
class ValidateForm(Action):
def name(self) -> Text:
return "user_quiz_form"
def run(
self, dispatcher: CollectingDispatcher, tracker: Tracker, domain: Dict
) -> List[EventType]:
required_slots = ["question1","question2", "question3"]
for slot_name in required_slots:
if tracker.slots.get(slot_name) is None:
# The slot is not filled yet. Request the user to fill this slot next.
return [SlotSet("requested_slot", slot_name)]
return [SlotSet("requested_slot", None)]
class ActionSubmit(Action):
def name(self) -> Text:
return "action_submit"
def run(
self,
dispatcher,
tracker: Tracker,
domain: "DomainDict",
) -> List[Dict[Text, Any]]:
print("****************SUBMIT*****************")
dispatcher.utter_message(template="utter_quiz_thanks", date=tracker.slots.get("question1"))
return []
When the form is triggered, it doesn't' ask the questions to the user and returns utter_quiz_thanks with None as question1 value.

Is this the same indentation you're using in your domain.yml? If so, you're missing some indents; the slots underneath the form need to be indented (see below for an example). My guess is that you're launching the form correctly, but due to the indent issues your assistant is treating it as a form with 0 questions.
forms:
restaurant_form:
cuisine:
- type: from_entity
entity: cuisine
num_people:
- type: from_entity
entity: number
