The first argument of your function contains the event that triggered the function, which is represented within AWS Lambda as a JSON object, but what is passed to Python is a dict of that object. But these were really just examples to help you get started with serverless development. I'm not sure non-linux would work with serverless since lambda inherently uses a linux OS.. non-linux means that it will use Docker for packages installation/building instead of your native OS for that exact reason.
