There are two scenarios where Node behaves different from most other Functions Frameworks

1. User throws an exception in their function code
2. User returns an error in their event-driven function code (HTTP functions don't have return parameters)

Most frameworks will return HTTP status code 500 in both those cases, and hide the exception/error message from the invoker.

Node returns 200 status code and returns the exception/error message in the response body. We should modify node to return 500 and omit the exception/error message from the response body to avoid leaking debug information to the invoker. We should log the message instead.
