I keep getting action_default_fallback after resetting the slots. I’m using custom action, and bool slot.

Stories.yml

stories:
  - story: greet and subscribe
    steps:
    - intent: greet
    - action: utter_greet 
    - intent: subscribe
    - action: newsletter_form
    - active_loop: newsletter_form
    - slot_was_set:
      - requested_slot: email
    - slot_was_set:
       - email: xy@tee.com
    - slot_was_set:
      - requested_slot: null
    - active_loop: null
    - action: utter_subscribed
    - checkpoint: ask_community

  - story: want to join community
    steps:
    - checkpoint: ask_community
    - action: utter_community
    - intent: affirm
    - action: action_join_community
    - slot_was_set:
      - join_community: True
    - action: utter_say_welcome
    - action: action_reset_slot
  
  
  - story: do not want to join community
    steps:
    - checkpoint: ask_community
    - action: utter_community
    - intent: deny
    - action: action_join_community
    - slot_was_set:
      - join_community: False
    - action: utter_say_goodbye
    - action: action_reset_slot

actions.py

          class ActionResetSlots(Action):
              def name(self) -> Text:                                                                                                
                   return "action_reset_slot"

             def run(self, dispatcher: CollectingDispatcher,
                     tracker: Tracker, domain: Dict[Text, Any]) -> List[Dict[Text, Any]]:

                    return [AllSlotsReset()]

             class ActionJoinCommunity(Action):
                     def name(self):
                           return "action_join_community"

                     def run(self, dispatcher, tracker, domain):
                          """Sets the slot 'join_community' to true/false dependent on whether the user
                    wants to join mail subscription"""
                          intent = tracker.latest_message["intent"].get("name")

                       if intent == "affirm":
                                return [SlotSet("join_community", True)]
                      elif intent == "deny":
                               return [SlotSet("join_community", False)]
                      return []

Any suggestions? Please ignore indentation problems

Which story is failing? Not sure if this is the problem here, but note that a bool slot really has 3 possible values: unset (null) ,true, and false. So doing a general reset of all slots will make the bool slot null, not false.

If you’re resetting all the slots at the end of the conversation, maybe you can just add this to your domain:

session_config:
  session_expiration_time: 60
  carry_over_slots_to_new_session: false
