Custom Action doesn't extract Slot with Role

Rasa Open Source
1

Hi ! I discover the release of Entity Roles a few days ago, and I was very excited because it’s exactly what I need.

So I tried to use it but I have a problem which I don’t understand.

In debug mode I can see that my entity with good roles are detected, but my slot are not filled :

Here, an extract of my debug of my action :

2020-05-25 13:29:55 **DEBUG** rasa_sdk.forms - Validating extracted slots: {} 
2020-05-25 13:29:55 **DEBUG** rasa_sdk.forms  - No slots left to request, all required slots are filled:
	action: deny

We can see that my city-site origin (Lyon) and destination (Milan) are recognized, but they are not extracted and used in my action.

Here, the beginning of my action, with the slot mapping.

class ActionCreateNewFWRule(FormAction):

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

    @staticmethod
    def required_slots(tracker: Tracker) -> List[Text]:
        """A list of required slots that the form has to fill"""
        return ["action"]

    def slot_mappings(self) -> Dict[Text, Any]:
        return {"action": self.from_entity(entity="moment",
                                                  intent=["action_added",
                                                          "reseau_action"]),
                "application": self.from_entity(entity="application",
                                                  intent=["reseau_action"]),
                "user": self.from_entity(entity="user",
                                                  intent=["reseau_action"]),
                "service": self.from_entity(entity="service",
                                                  intent=["reseau_action"]),
                "site_source": self.from_entity(entity="city-site", role="origin"),
                "site_destination": self.from_entity(entity="city-site", role="destination"),
                "department_source": self.from_entity(entity="department", role="origin"),
                "department_destination": self.from_entity(entity="department", role="destination"),
                "site_group_source": self.from_entity(entity="site_group", role="origin"),
                "site_group_destination": self.from_entity(entity="site_group", role="destination"),
                "address_source": self.from_entity(entity="address", role="origin"),
                "address_destination": self.from_entity(entity="address", role="destination")}

I don’t want to put this slot in required because the user can be not precise them.

I hope you will can help me, because I don’t understand, I followed the tutorial about this : Introducing entity roles and groups

Thank you

EDIT : Finally, I think my problem is that my slots are not filled if the slot name is not the same of a entity name, but I don’t know why.

Finally, I thought my problem isn’t that, so I created an other post (If a slot is not requested, slot mapping doesn't work) I think the problem is about slot name and entity name that aren’t the same.

So I close this one.

thank you
