I'm struggling with rasa for a little while now: I'm trying the example (inspired from rasa doc /) stories:

- story: interactive_story_1
  steps:
  - intent: welcome
    entities:
    - passport_form_status: true
  - slot_was_set:
    - passport_form_status: true
  - action: utter_welcome

- story: interactive_story_2
  steps:
  - intent: welcome
    entities:
    - passport_form_status: false
  - slot_was_set:
    - passport_form_status: false
  - action: utter_welcome_back

domain

version: '3.1'
entities:
- passport_form_status
slots:
  passport_form_status:
    type: bool
    initial_value: false
    influence_conversation: false
    mappings:
    - type: from_entity
      entity: passport_form_status
intents:
- affirm
- bot_challenge
- deny
- goodbye
- greet
- mood_great
- mood_unhappy
- welcome
responses:
  utter_greet:
  - text: Hey! How are you?
  utter_cheer_up:
  - text: 'Here is something to cheer you up:'
    image: .jpg
  utter_did_that_help:
  - text: Did that help you?
  utter_happy:
  - text: Great, carry on!
  utter_goodbye:
  - text: Bye
  utter_iamabot:
  - text: I am a bot, powered by Rasa.
  utter_welcome:
  - text: Welcome
  utter_welcome_back:
  - text: Welcome back
session_config:
  session_expiration_time: 60
  carry_over_slots_to_new_session: true
actions:
- utter_welcome
- utter_welcome_back

but the result is not the one expected. Bot loaded. Type a message and press enter (use '/stop' to exit):

Your input ->  /welcome{"passport_form_status": true}                                                                                                                                                                                                                                                                                                                     
Welcome back
Your input ->  /welcome{"passport_form_status": false}                                                                                                                                                                                                                                                                                                                    
Welcome back
Your input ->   

Expected /welcome{"passport_form_status": true} to display Welcome

Can anyone shed a light on this? Thanks!
