The code that was changed in multiple files used ‘utter\_slots\_values’ which I changed to ‘utter\_slots\_values\_restaurant’ in the appropriate files. I grepped the directory to ensure that I changed all references for ‘utter\_slots\_values’. Now when I run rasa train I get the message `WARNING rasa.core.domain - Failed to use action 'utter_slots_values' in history. Please make sure all actions are listed in the domains action list. If you recently removed an action, don't worry about this warning. It should stop appearing after a while.` I’ve run rasa train about 10 times but I still get this message. Even though I ran the code successfully many times, once I renamed the function, rasa train has continued to look for the old function name. How can I get rasa train to work?

NOTE: some of the code that I pasted is converted to bullets since I chose the editor option to pre-format the code output below. The code I posted uses the proper formatting - no syntax errors. Code in domain.yml utter\_slots\_values\_restaurant:

- text: “I am going to run a restaurant search using the following parameters:\n  
\ - cuisine: {cuisine}\n - num\_people: {num\_people}\n - outdoor\_seating: {outdoor\_seating}\n  
\ - preferences: {preferences}\n - feedback: {feedback}”

Code in stories.md

## happy path

- greet
  - utter\_greet

- request\_restaurant
  - restaurant\_form
  - form{“name”: “restaurant\_form”}
  - form{“name”: null}
  - utter\_slots\_values\_restaurant

Here’s some of the output: 2019-11-01 16:54:28 WARNING rasa.core.domain - Failed to use action ‘utter\_slots\_values’ in history. Please make sure all actions are listed in the domains action list. If you recently removed an action, don’t worry about this warning.

Did you also update the name of the template in the `actions` sections in the `domain.yml`?

I just found the issue - while I did update the name of the template, there were other references that I found. When I updated them to the new action name, rasa train worked perfectly. Thanks!
