Categorical Slot - category is not picked in the story line

Rasa Open Source
1

Hi,

I have implemented the categorical slot in my story. My categorical slot is getting set from the custom actions that I have defined in actions.py file. The story which I have defined should only follow when my booking status is cancelled. But even if my booking status is some other value other than cancelled, the story is getting picked.

Kindly help me with this issue.

My stories.yml file

- story: Cancelled status story
  steps:
  - intent: modify_booking_status_noshow_with_invoice_no
    entities:
    - invoice_no: B8H07344
  - slot_was_set:
    - invoice_no: B8H07344
  - action: action_extract_booking_status
  - slot_was_set:
    - booking_status: cancelled
  - action: utter_noshow_process_details_cancelled

Here is my actions.py file

class ActionBookingStatus(Action):

    def name(self) -> Text:
        return "action_extract_booking_status"

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

        bookingInvoice = tracker.get_slot("invoice_no")

        if bookingInvoice == 'ZUJR0078':
            bookingIdStatus = 'confirmed'
            dispatcher.utter_template("utter_booking_status", tracker, bookingStatus=bookingIdStatus)

        elif bookingInvoice == 'IAI15508':
            bookingIdStatus = 'check in'
            dispatcher.utter_template("utter_booking_status", tracker, bookingStatus=bookingIdStatus)

        elif bookingInvoice == 'HFHG6514':
            bookingIdStatus = 'check out'
            dispatcher.utter_template("utter_booking_status", tracker, bookingStatus=bookingIdStatus)

        elif bookingInvoice == 'B8H07344':
            bookingIdStatus = 'cancelled'
            dispatcher.utter_template("utter_booking_status", tracker, bookingStatus=bookingIdStatus)

        elif bookingInvoice == 'ER637550':
            bookingIdStatus = 'no show'
            dispatcher.utter_template("utter_booking_status", tracker, bookingStatus=bookingIdStatus)

        return [SlotSet("booking_status", bookingIdStatus)]
