Slot_was_set is not working as expected

Rasa Open Source
1

Hi! I’m using Rasa 3.6.13-full version and currenctly I’m facing a issue when using slot_was_set as a condition in my rules.

I have these rules, the first one I want to run when the user is greeting the bot for the first time in the session. I want the bot to say “hi” as well, send the user a message with tips on how to use the bot, and then trigger a form to fill a slot related to the user’s identity.

The second rule handles the cases where the user says “hi” to the bot again in the same session. I don’t need to fill the slot again and I don’t want to send chat chips, so I just send a response with something like “hi again”.

rules:

- rule: Greet The User and Activate cnpj form
  condition:
      - slot_was_set:
        - user_was_greeted: false
  steps:
    - intent: greet
    - action: greet_the_user
    - action: action_help_with_features
    - action: cnpj_form
    - active_loop: cnpj_form


- rule: Just Greet The User Again
  condition:
    - slot_was_set:
      - user_was_greeted: true
  steps:
    - intent: greet
    - action: utter_greet_again

# OTHER RULES ...

The problem is:

When I greet the bot for the first time, my Custom Action (you can see the code below) is triggered correctly, BUT the other actions that follow are not executed. I suspect this is because when I use SlotSet and set the slot value to True, Rasa triggers the second rule and ignores the rest of the first one.

class ActionGreetTheUser(Action):
    def name(self) -> Text:
        return "greet_the_user"

    async def run(
            self,
            dispatcher: CollectingDispatcher,
            tracker: Tracker,
            domain: Dict[Text, Any],) -> List[Dict[Text, Any]]:

        Debugger().info(f"ActionGreetTheUser.run: tracker.slots={tracker.slots}")

        dispatcher.utter_message(response=UTTER_GREET)
        dispatcher.utter_message(response=UTTER_IAMBOT)

        return [SlotSet("user_was_greeted", True)]

Can anyone help me?

Other solutions to execute different paths when the user greets the bot are also welcome! :slightly_smiling_face:

I am having the same kind of problems. Reading the documentation and even some code examples, I was expecting that it would work just as you’ve described. In some cases, the execution takes a different flow from the intended one, creating bugs such as reported by your post, where a set happens, apparently, before it should have happened. This is most likely a bug from Rasa, since it wouldn’t make sense that this is the expected behavior, enforcing some workarounds for it to properly work.
