在 Rasa 2 的自定义操作中返回 SlotSet 时未触发下一个规则操作

Question

我有以下规则：

- rule: submit form
  condition:
  - active_loop: user_offer_form
  steps:
  - action: user_offer_form
  - active_loop: null
  - slot_was_set:
    - requested_slot: null
  - action: action_get_offer
  - action: utter_ask_deal

这是自定义操作：

class ActionGetOffer(Action):
def name(self) -> Text:
    return "action_get_offer"

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

    dispatcher.utter_message(text = "Ok! Let me see what I can do!")


    product_price = 500
    platform_bargain_percentage = 5
    vendor_bargain_percentage = 5
    max_bargain = platform_bargain_percentage + vendor_bargain_percentage

    offer_price = int(tracker.get_slot("price"))
    print(offer_price)

    user_asked_percentage = (offer_price / product_price) * 100

    current_bargain = tracker.get_slot('current_bargain') + 2
    print(current_bargain)



    if user_asked_percentage > current_bargain:

    
        dispatcher.utter_message(text = "Okay so I just checked and sorry but we can't give away for that price!")

        if tracker.get_slot('current_bargain_price') == 0:
            current_bargain_price = (product_price - (((current_bargain)/100) * product_price))
        else:
            current_bargain_price = tracker.get_slot('current_bargain_price')

        if current_bargain <= max_bargain:
            dispatcher.utter_message(text = f"How about {str( product_price - (((current_bargain)/100) * product_price))}?")
        else:
            dispatcher.utter_message(text = "Hmm...wanna make a fresh offer then?")


        # dispatcher.utter_message(response = 'utter_ask_deal')
        return[SlotSet("current_bargain", value = float(current_bargain))]

这里是 utter_ask_deal：

  utter_ask_deal:
    - text: "Ok with this deal?"
      buttons:
      - title: "Yup"
        payload: '/inform_intent{{"deal":"true"}}'
      - title: "Nope"
        payload: '/inform_intent{{"deal":"false"}}'

规则一直执行到action_get_offer，但utter_ask_deal 没有得到执行，槽‘current_bargain’ 也没有得到更新。

有趣的是，当我不在 return 语句中使用 SlotSet 而是直接在代码中使用它时，正在执行下一个操作，但在这两种情况下都不会更新 slot。

有人可以帮忙吗？

机器人话语utter_ask_deal 在buttons 标记周围有缩进问题，请尝试将其更改为：

utter_ask_deal:
- text: "Ok with this deal?"
  buttons:
  - title: "Yup"
    payload: '/inform_intent{{"deal":"true"}}'
  - title: "Nope"
    payload: '/inform_intent{{"deal":"false"}}'
