actions:

- utter_happy

- action_outofscope
- utter_outofscope

Removing triggers: action_outofscope from the domain file doesn't raise the error.

Thanks for raising this issue, @tabergma will get back to you about it soon✨

Please also check out the docs and the forum in case your issue was raised there too 🤗

[tabergma]

I think you are missing an indent:

intents:
- greet
- goodbye
- affirm
- deny
- mood_great
- mood_unhappy
- out_of_scope:
    triggers: action_outofscope

esponses:
  utter_greet:
  - text: Hey! How are you?
  utter_cheer_up:
  - text: 'Here is something to cheer you up:'
    image: https://i.imgur.com/nGF1K8f.jpg
  utter_did_that_help:
  - text: Did that help you?
  utter_happy:
  - text: Great, carry on!
  utter_goodbye:
  - text: Bye
utter_outofscope:
  - text: Sorry, I can’t handle that request.

actions:
- utter_greet
- utter_cheer_up
- utter_did_that_help
- utter_happy
- utter_goodbye
- action_outofscope
- utter_outofscope

Does it work with this domain file?

• out_of_scope:
  triggers: action_outofscope

triggers must be indent

@shixx299 I'm going to close the issue as it is not a bug. Glad it works now 😄
