"""
Create a lambda_handler and catch any import errors
This is kind of gross, but it was the easiest way I found to persist the info in e into the function definition.
The problem is that the act of importing the bottle app causes startup code to run.
Perhaps we can refactor the bottle app so that the app is created here?
