+Similarly, the _ExceptionHandler_ does what it sound like: it catches any exceptions that bubble up through the subsequent middleware decorators.
 
 The _ExceptionHandler_ does nothing with the `$request` or `$response`, and passes them directly to `$next` inside a `try/catch` block. If no exception bubbles up, it returns the `$response` from `$next`.  However, if it catches an exception, it returns an entirely new `$response` object with the exception message and an HTTP 500 status code. It then returns the new `$response` object.
