Custom actions not working since last update (if - else statement only takes else)

Rasa Open Source

I use a form and check if the content of the slots matches with the symptoms for a cold, if not it matches with symptoms with a flu. Wich worked fine during the last weeks. Today I updates Rasa X (now 0.34.0) and Rasa (now 2.1.3) and I get only what happens under “else” although I make my answers true for “if”. I checked multiple times if there could be a typo, but there isn’t. Any ideas?

The actions.py looks like this:

class SymptomQuizDiseases:
    cold = [["discomfort_slow", "symptom_light", "false", "false", "feel_listless"], ... ]]
    responseCold = "It's a cold."
 
    flu = [["discomfort_fast", "symptom_heavy", "true", "true", "feel_bad"], ... ]
    responseFlu = "It's a flu."

class SymptomQuizSubmission(Action):

    def name(self):
        return "submit_symptom_quiz_result"

    def run(
        self, dispatcher: CollectingDispatcher, tracker: Tracker, domain: DomainDict
    ):
        
        slot_list = [tracker.get_slot("discomfort_beginning"),tracker.get_slot("discomfort_development"),tracker.get_slot("temperature"),tracker.get_slot("body_aches"),tracker.get_slot("physical_condition")]
    
        if slot_list in SymptomQuizDiseases.cold:
            dispatcher.utter_message(SymptomQuizDiseases.responseCold)
        else: 
            dispatcher.utter_message(SymptomQuizDiseases.responseFlu)
           
        return []

The form part of my domain.yml

    forms:
      symptom_quiz_form:
        body_aches:
        - intent: affirm
          type: from_intent
          value: true
        - intent: deny
          type: from_intent
          value: false
        discomfort_beginning:
        - intent: feel_bad
          type: from_intent
          value: discomfort_fast
        - intent: slow
          type: from_intent
          value: discomfort_slow
        discomfort_development:
        - intent: feel_bad
          type: from_intent
          value: symptom_heavy
        - intent: symptom_light
          type: from_intent
          value: symptom_light
        physical_condition:
        - intent: feel_bad
          type: from_intent
          value: feel_bad
        - intent: feel_listless
          type: from_intent
          value: feel_listless
        temperature:
        - intent: affirm
          type: from_intent
          value: true
        - intent: deny
          type: from_intent
          value: false

Found the mistake myself: It is now necessary to use bool instead of str in actions.py if I set the value to true or false in the domain.yml

Can you please explain this better?
