Hi Team, I try to implement fallback policy as per rasa documentation.I have created rasa sample project in rasa 2.1.2 and added extra intent in nlu file.

- intent: out\_of\_scope

in rule.yml file:

- rule: out-of-scope

domain.yml file: intent section: out\_of\_scope

response section: utter\_out\_of\_scope:

```
- text: Sorry, I didn't get what you said. Please rephrase what you said.

```

config.yml file: pipeline section:

- name: WhitespaceTokenizer

policis section:

- name: MemoizationPolicy

Please help to sort out this issue. Regards, subbu.

you could run rasa shell --debug to check what intent your assistant is recognizing. Even run rasa interactive and teach your bot what kind of expressions are out of scope and how it should respond …
