Slots not resetting with action_deactivation_loop

Operating System : macOS-10.14.6-x86_64-i386-64bit

Issue:
Slots are not resetting after form de-activation is called. I was told to create a ticket in this forum thread

Stories solution:

• story: User stops health_form
  steps:
  • active_loop: health_form
  • intent: flush_slots
  • action: action_flush_slots
  • action: utter_start_over
  • action: utter_greet
  • action: action_deactivate_loop
  • active_loop: null

description
Because action_deactivation_loop dosen't reset the slots, I added a custom action with the trigger

class ActionFlushSlots(Action):
    
    def name(self) -> Text:
        return "action_flush_slots"

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

        slots = []
        for key, value in tracker.current_slot_values().items():
            if value is not None:
                slots.append(SlotSet(key=key, value=None))

        return slots

@travelmail26 What's the complete stack trace?
And what are you trying to do when?

Hi @travelmail26 In absence of the complete stack trace, I've replicated the InvalidRule behaviour you described in the forum post - this I gathered is owed to the fact that action_deactivate_loop was placed outside of an active form because the health form was already deactivated via active_loop: null in the example you provided in the forum post:

- rule: Submit form
  condition:
    # Condition that form is active.
    - active_loop: health_form
  steps:
  - action: health_form
  - active_loop: null
    # The action we want to run when the form is submitted.
  - action: action_submit_results
  - action: utter_slots_values
  - action: action_deactivate_loop
  - active_loop: null

I also agree with @wochinge that the correct way currently to reset the slots is via custom action because action_deactivate_loop has the same function as active_loop: null to inactivate/ exit the form and is best used to handle unhappy form paths.

The solution I see here is for us to update docs so that it's clear what's the recommended route for resetting slots using AllSlotsResetevent returned by a custom action after form submission. Would that work?

in order to use function"SLotSet()",which lib should i import?

SlotSet is not a function, is an object. You can import SlotSet in your actions.py like so:
from rasa_sdk.events import SlotSet
