When i try to implement 2 stage fallback policy in rasa 2.0 i get this error No registered action found for name ‘action\_default\_fallback’.

**Config.yml** policies:

# # No configuration for policies was provided. The following default policies were used to train your model.

# # If you’d like to customize them, uncomment and adjust the policies.

# # See [Policy Overview | Rasa Documentation](https://rasa.com/docs/rasa/policies) for more information.

- name: MemoizationPolicy

- name: MappingPolicy

- name: TEDPolicy

- name: RulePolicy

- name: TwoStageFallbackPolicy

**Domain.yml** utter\_ask\_affirmation:

- text: “Hey! Did you mean?”

utter\_ask\_rephrase:

- text: “Can you please rephrase your input! 😅”

utter\_default:

- text: “Sorry this is a default message ,didn’t get that please try again!😅”

actions:

- action\_default\_fallback

Else, can you share your config.yml file? or copy paste this in config.yml, train and run. delete previous models.

Hope it will solve your issue.
