@Abhinav there are two issues with your file:

  1. - about_us: {triggers: action_about_us} This is the 1.x format for the MappingPolicy. This has been deprecated in favor of writing Rules.

  2. there’s an extra - for this response causing the error:

    - image: https://i.imgur.com/nGF1K8f.jpg
    - text: Here is something to cheer you up

If you change it to this it works:

  utter_cheer_up:
    - text: Here is something to cheer you up

I’ll add onto the GitHub Issue that we’re missing the explanation for what’s wrong with the file in our output.
