I have followed rasa documentation on custom slot mapping but I still get my rasa form unable to extract slot. I have a form with six input of which only one is connected to an entity. Below is my actions.py file:
class ActionFormInfo(FormAction):
def name(self) -> Text:
"""Unique identifier of the form"""
return "form_filling"
@staticmethod
def required_slots(tracker: Tracker) -> List[Text]:
"""A list of required slots that the form has to fill"""
service = tracker.get_slot('SERVICE')
if tracker.get_slot('PICKUP') == 'YES':
return ["KG", "FULLNAME", "PHONE", "PICKUP", "ADDRESS"]
else:
return ["KG", "FULLNAME", "PHONE", "PICKUP"]
