Custom fallback action not found

Hi, I am trying to create a custom fallback action and executing it I am getting the following error:

No registered Action found for name ‘action_my_fallback’.

Here my confs:

policies.yml policies:

  • name: KerasPolicy epochs: 200 max_history: 3
  • name: MemoizationPolicy max_history: 3
  • name: FormPolicy
  • name: “FallbackPolicy” nlu_threshold: 0.5 core_threshold: 0.5 fallback_action_name: ‘action_my_fallback’

domain.yml actions:

  • action_my_fallback templates: utter_default:
    • text: “default”

class ActionMyFallback(Action): def name(self): # type: () -> Text return “action_my_fallback”

def run(self, dispatcher, tracker, domain):

dispatcher.utter_message("Asking question")

return [ActionReverted()]

I also tried returning UserUtteranceReverted

Mhm, did you connect your action server to Rasa Core using the endpoints.yml? And what’s the log output of the Rasa Core SDK server if you start it?

Problem was fixed after restart my PC thanks
