Slots not getting filled up, after utter_ask_slotname in a form

Rasa Open Source
1

Hi! I am using Rasa3.1. The bot runs utter_ask_<slot_name>, but after receiving an input, it did not store the value as the required slot. Instead, it repeats utter_ask_<slot_name>.

What am I missing?

domain.yml

utter_ask_depgroup:
  - text: Okay, got it! Are the dependent variables 'categorical' or 'numerical' or 'factors' or 'count' or 'time to event'?
  utter_ask_indepgroup:
  - text: Great! Are the independent variables 'categorical', 'numerical' or 'factors/covariates'?

You should follow the example rules/stories from the forms documentation. That long story is likely the problem.

Thank you @stephens! The slots get filled when I changed the slot mapping type (from_entity to from_text). Details:

domain.yml

   indepgroup:
    type: list
    influence_conversation: true
    mappings:
      - type: from_text
        conditions:
         - active_loop: info_test_form
           requested_slot: indepgroup
