  }
}

I have used a default setup, I think.

I suspect that I haven’t set up the Step-Function correctly or when I did some research into the error I might not have given sufficient permission to the “index.handler” or Zip etc.

The best way to fix this problem for good is to use an automated tool like serverless and let the tool handle the folder structure and deployment for you. checkout this link
