Having only custom slot mapping in rasa 2.1.3 forms

Hi

I have been trying to implement forms in rasa 2.1.3. I am filling all the slot with custom slot mapping and according to documentation here, i should only mention slots that use pre-defined mapping in the domain.yml. so here is what my domain.yml looks like for forms.

slots:
  avdt_flag:
    type: text
    influence_conversation: true
forms:
  comparison_form
responses:
  utter_begin_comparison:
  - text: Lets compare!

But this is not working. None of my required slots are getting filled. Here is my actions.py.

class AskForSlotActionCompareWhat(Action):
    def name(self) -> Text:
        return "action_ask_compare_what"

    def run(
        self, dispatcher: CollectingDispatcher, tracker: Tracker, domain: Dict
    ) -> List[EventType]:
        metric_candidates = ['visits', 'visitors']
        button_info = {"1": metric_candidates}
        message, buttons = button_shower(
                                            self.name(),
                                            button_info,
                                            tag="1"
                                            )
        print(message)
        print(buttons)
        dispatcher.utter_message(
                    text=message,
                    buttons=buttons)
        return []

    ) -> List[EventType]:

                                        "comparison_timeperiods").keys())
        button_info = {"1": tscale_candidates}
        message, buttons = button_shower(

                                            )
        dispatcher.utter_message(
                    text="",
                    buttons=buttons)
        return []

@akelad Is there something missing as its not working. Not even the actions to ask for slots are getting executed. How to make it work? I also checked this issue on github issue but its not clear.

Hey @akelad any solution here ? I am facing the same issue. How should one use custom slot mappings if the forms slots are only using custom slot mapping. My rasa version is 2.2.8

Hi,

I have the same problem and question. I want to use only custom slot mappings but it doesn’t seem to work. My rasa version is 2.4.0. Has somebody any idea? The problem is discuessed here and as i understand also solved but it doesn’t work.

Is there any solution for this issue to have forms with only custom slot mappings?
