Hi @vidhya03

You can't run this action on the following events. It's designed to run on issue_comment.

  pull_request:
    types: [opened, synchronize]

Also, the action creates a repository_dispatch event. You need to have a workflow that is triggered by that event.

I suggest doing the getting started tutorial so that you have a working base. Then you can make changes slowly to understand how it works.
