Hi, suppose in slot mapping I mentioned

> “customer\_id”: self.from\_entity(entity=“customer\_id”,not\_intent=[‘stop’])

In validation of this slot I mentioned that

> ```
> if not self.is_int(value):
> dispatcher.utter_template("utter_invalid_customer_id", tracker)
> return {"customer_id": None}
> else:
> return {"customer_id": value}
> 
> ```

In story

> ```
> - form{"name": "bank_form"}
> 
> ```
> 
> - form: stop
> - utter\_ask\_continue
> 
> - form: deny
> - action\_deactivate\_form
> - form{“name”: null}

So, 1. Once the form is called it will ask user to fill this slot → this is handled. 2. But when user gives input to this slot as “stop” intent, the form still validates “None” …

How Can I avoid this validation? (when stop intent is uttered)
