How to add default greeting action in story?

Hello, I use http://localhost:5005/conversations/{conversation_id}/execute to set default greeting message. In the action, I dispatched 2 utter_template: greet, bot functionality introduction

I set the story as following but does not work:

  • action_greet_user
  • utter_template_greet
  • utter_template _introduction
  • ask_for_quotation
  • form
  • …other things

Rasa correctly dectectd my intent as “ask_for_quotation”, but returns with 2 action_default_fallback and send me back to action_listen. In the action_greet_user function, I tried return [FollowupAction(‘action_listen’)] and return[] with no luck. Rasa cannot predict accroding to my story.

Please help

Is it due to policy setting?

my config.yml: language: en pipeline: supervised_embeddings policies:

  • name: FormPolicy
  • name: FallbackPolicy
  • name: MemoizationPolicy
  • name: MappingPolicy
  • name: KerasPolicy

it uses the policy_1_FallbackPolicy with 0.3 confidence to go back.
