    """Register an exception handler for logging or processing.
    This method allows the registration of a custom exception handler to
    catch and process exceptions that occur in the application. Unlike a
    typical exception handler that might modify the response to the client,
    this is intended to capture exceptions for logging or other internal
    processing, such as sending them to an error reporting utility.
    Args:
        handler (Callable): A coroutine function that takes the application
            instance and the exception as arguments. It will be called when
            an exception occurs within the application's lifecycle.
    Example:
        ```python
        app = Sanic("TestApp")
        @app.catch_exception
        async def report_exception(app: Sanic, exception: Exception):
            logging.error(f"An exception occurred: {exception}")
            # Send to an error reporting service
            await error_service.report(exception)
        # Any unhandled exceptions within the application will now be
        # logged and reported to the error service.
        ```

        await handler(self, exception)
