RASA3.1: Form cannot obtain the value set in NLU

Rasa Open Source
1

A few days ago, I used RASA open source. But when I started using Form to retrieve certain fields in the user’s intent, it was unable to retrieve the data or trigger the intent. The following is the yaml configuration file:

All ymls are version 3.1

nlu.yml：

- intent: info_input_name
  examples: |
    - Help me check [nlu](user_input_name)
    - 
Please help me check [nlu](user_input_name)

domain.yml:

forms:
  name_form:
    required_slots:
      - user_input_name
 
responses:
  utter_output_name:
  - text: "OK,I know you‘re {user_input_name} now"
 
entities:
  - user_input_name  
 
 
slots:
  user_input_name:
    type: text
    influence_conversation: false
    mappings: 
    - type: from_entity
      entity: user_input_name

rules.yml:

rules:
- rule: avtivate user_input_name form
  steps:
  - intent: info_input_name
  - action: name_form
  - active_loop: name_form
 
- rule: stop user_input_name form
  condition:
  - active_loop: name_form
  steps:
  - action: name_form
  - active_loop: null
  - slot_was_set:
    - requested_slot: null
  - action: action_getSexByName
  - action: utter_output_name

action:


class ActionGetSexByName(Action):
 
    def name(self):
 
        return 'action_getSexByName'
 
    def run(self, dispatcher, tracker, domain):
 
        content = tracker.latest_message
        # .intent.entities.value
        # content[0]
        vall = tracker.get_slot("user_input_name")
 
        print("content:")
        print(content)
 
        print("slot:")
        print(vall)
        return []

Please help me!!!

I don’t see a definition for utter_ask_user_input_name.

utter_ask_user_input_name What does this mean, please?Do I need to define this? Do you mean utter_output_name?
