Rasa custom actions events are lost - rasa-core

Question

I'm trying to implement custom actions and have added action_get_answer to domain.yml.
actions:
- utter_greet
- utter_cheer_up
- utter_did_that_help
- utter_happy
- utter_goodbye
- actions.GetAnswer
Added the action in actions.py :
class GetAnswer(Action):
def name(self) -> Text:
return "action_get_answer"
def run(self, dispatcher: CollectingDispatcher,
tracker: Tracker,
domain: Dict[Text, Any]) -> List[Dict[Text, Any]]:
dispatcher.utter_message("action_get_answer")
return []
Ran the action server:
$ rasa run actions
Upon running rasa server :
$ rasa x
i get this error and GetAnswer is not triggered -
ERROR rasa.core.processor - Encountered an exception while running
action 'action_get_answer'. Bot will continue, but the actions events
are lost. Make sure to fix the exception in your custom code.
How do I make this work?
Thanks

I am also working on RASA X. I have created custom actions and it is successfully called. But first I want to know, does your stories.md file contain that action ? means when to call that action.
Here I am giving what I have implemented :
In stories.md file :-
## story1
* play
- action_ask_question
In domain.yml file :-
...
actions:
- action_ask_question
...
In action.py file :-
class ActionAskQuestion(Action):
def name(self):
return "action_ask_question"
def run(self, dispatcher, tracker, domain):
dispatcher.utter_message("Action called.")
return []
If you have any question, comment it.

I also had this error while using custom actions in Rasa (not Rasa X).

I sloved the problem by adding action endpoints to endpoints.yml file
action_endpoint:
url: "http://localhost:5055/webhook"
run actions server using one command-line
rasa run actions
or (if you had not installed rasa)
python -m rasa_sdk --actions actions
and run rasa shell using another command-line (with endpoint configurations)
rasa shell --endpoints endpoints.yml
