        routing_api = func(*args, **kwargs)
        async def api_handle(request: Request) -> Response:
                http_response = await routing_api(request)
            except Exception as ex:

    return routing_wrapper
routing.get_request_handler = handle_wrapper(routing.get_request_handler)
