Slot is not filled from_text in Rasa 3.0

Rasa Open Source

Hi Rasa community,

I try to fill two slots in a form from_text but in rasa interactive it always misclassifies the intent (actually it should not classify any intent as the message is only filled from the user response) and the slots keep staying empty. I have found this issue already on GitHub (https://github.com/RasaHQ/rasa/issues/10053) but there does not seem to be any solution/explanation for it.

This is how my code looks like:

slots:
  nick_name:
    type: text
    influence_conversation: true
    mappings:
    - type: from_text
      conditions:
      - active_loop: start_form
        requested_slot: nick_name
  favorite_dish:
    type: text
    influence_conversation: true
    mappings:
    - type: from_text
      conditions:
      - active_loop: start_form
        requested_slot: favorite_dish

forms: 
  start_form: 
    required_slots: 
      - nick_name
      - favorite_dish

This is the corresponding story:

stories:

- story: happy path cold shower start
  steps:
  - intent: greet
  - action: utter_greet
  - action: action_start_conversation
  - intent: affirm
  - action: start_form
  - active_loop: start_form
  - slot_was_set:
    - requested_slot: nick_name
  - slot_was_set:
    - nick_name: hansi
  - slot_was_set:
    - requested_slot: favorite_dish
  - slot_was_set:
    - favorite_dish: rice
  - slot_was_set:
    - requested_slot: null
  - active_loop: null
  - action: utter_same_dish
  - action: action_start_topic

I do not need to get the actual entities or intents. The user can say anything for their nick_name and the bot should just record it. Same for fav_dish. The bot will just always answer “good choice”. It is to test the from_text feature but the slots do not get filled. I hope someone can point me to my mistake… Maybe I do need to classify an intent? But how would I then provide training data for the intent as I do not want to give examples for the nick_name as it could be literally anything from “Banana” to “John” to “Superhero”?

Many thanks!

I suggest you make a couple of changes to follow the best practices for forms as shown in the docs.

There should be a simple formactivate and submit rule.

Don’t carry over the slot_was_set from your stories to the new rule (these are not necessary since the form required_slots will determine the order of slot prompts).

Drop the slot conditions:

      conditions:
      - active_loop: start_form
        requested_slot: favorite_dish
