1) You should usually use "except Exception:" rather than a bare except, even there. 2) When you create a boundary, *you log the exception*. That's what you're missing. Simply *suppressing* all exceptions is a terrible thing to do. It's common to have a web service boundary that says "except Exception as e: log_exception(e); return HTTP(500)", but that's not suppressing it, it's handling it.
