Form Action: validate_slot_name is not working

I have defined FormAction to retrieve two slots. In this case, slot name and the entity name are different and this is not calling the validate_slot_name function where I have handled the entity. Below is the FormAction code.

class PriceRelatedInfoForm(FormAction):

    def name(self):
        return "price_related_info_form"

    def required_slots(tracker):
        return ["p_test_name", "p_location"]

    def slot_mapping(self):
        return {
            "p_test_name": [self.from_entity(entity="test_name")],
            "p_location": [self.from_entity(entity="location"),

    def validate_p_test_name(self, value, dispatcher, tracker, domain):
        print("entity", tracker.get_latest_entity_values("test_name"))
        if any(tracker.get_latest_entity_values("test_name")) or any(tracker.get_latest_entity_values("p_test_name")):
            return {"p_test_name": value}
            dispatcher.utter_message(" Hmm, I'm not sure that's a valid test name, please make sure select the below options.")
            return {"p_test_name": None}

    def validate_p_location(self, value, dispatcher, tracker, domain):
        if any(tracker.get_latest_entity_values("GPE")) or any(tracker.get_latest_entity_values("location")):
            return {"p_location": value}
            dispatcher.utter_message("Not a valid city. Please enter the valid city.")
            return {"p_location": None}`

I don’t know what’s wrong. I have noticed similar example in Sara - the Rasa Demo Bot Here SalesForm has a slot (business_email) and entity (email) which has validate function to map the these two attributes. Please let me know what wrong I’m doing.

You can correct your validate

def validate_p_test_name(
        self, value, dispatcher, tracker, domain
    ) -> Dict[Text, Any]:
def validate_p_location(
        self, value, dispatcher, tracker, domain
    ) -> Dict[Text, Any]:

You need to provide a submit function don’t forget to check your slot_mapping function
