FormAction Submit fails to use dispatcher

Rasa version: 1.5.0 Python version: 3.6.8

Operating system: Windows 10

Issue:

After succesfully asking for every slot to be filled, the bot submits the form. Inside the submit method, I am using a custom utterance:

        response = dict(
            x=tracker.get_slot('x'),
            y=tracker.get_slot('y'),
            z=tracker.get_slot('z'),
            a=tracker.get_slot('a'),
            b=tracker.get_slot('b'),
            text='utter_submit_success'
        )
        dispatcher.utter_message(json_message=response)
        return []

Since you marked the other utterance-methods as deprecated, I am now testing this one. The following code lies in executor.py of rasa_sdk:

        message = {
            "text": text,
            "buttons": buttons,
            "elements": elements,
            "custom": json_message,
            "template": template,
            "image": image,
            "attachment": attachment,
        }
        message.update(kwargs)
        print(message)

        self.messages.append(message)

and results in:

2019-11-27 17:31:00 DEBUG    rasa_sdk.forms  - No slots left to request, all required slots are filled:
        x: True
        y: 4
        z: ['4', '4']
        a: 4sdf
2019-11-27 17:31:00 DEBUG    rasa_sdk.forms  - Submitting the form 'incident_form'
{'text': None, 'buttons': None, 'elements': (), 'custom': {'x': True, 'y': '4', 'z': ['4', '4'], 'a': '4sdf', 'b': None, 'text': 'utter_submit_success'}, 'template': None, 'image': None, 'attachment': None}
2019-11-27 17:31:00 DEBUG    rasa_sdk.forms  - Deactivating the form 'incident_form'
2019-11-27 17:31:00 DEBUG    rasa_sdk.executor  - Finished running 'incident_form'

So there is no error, but _utter_responses which iterates over the dispatchers utterances is never triggered aswell whereas while filling the slots, it actually is triggered.

So it seems that messages sent out of the submit method aren’t parsed. Am I doing something wrong?

Perfect. It works! 😃

Exactly - the print statement was added to make sure that the utterance itsself is generated correctly. It seems to me that it does not get processed.
