Slot filling with from_text

Rasa Open Source
1

I am using rasa form and trying to fill slot with text entered by user.

Slot filling works fine for 1st slot user_type. For 2nd slot user_name, i want slot to be filled with any text entered by user & hence using from_text. But this is not working for me.

am i missing anything here?

here is form detail in domain.yml

forms:
  user_info_form:
    required_slots:
      user_type:
      - type: from_entity
        entity: user_type
        intent:
          - user_type 
      user_name:
      - type: from_text
        intent: None

here is responses section

# user_info_form
  utter_ask_user_info_form_user_type:
  - text: As you are here for first time, it will be good to know about you. Who are you? 
      Parent / Student?
    channel: twilio
  - text: As you are here for first time, it will be good to know about you. Who are you?
    buttons:
    - payload: /user_type{{"user_type":"Parent"}}
      title: Parent
    - payload: /user_type{{"user_type":"Student"}}
      title: Student
  utter_ask_user_info_form_user_name:
  - text: May I have your First name please

this is solved.

need to use

user_name:
      - type: from_text

rather than

user_name:
      - type: from_text
        intent: None
