code: async def handle_http_exception(self, error: Exception) -> Response:
          
          handler = self._find_exception_handler(error)
          if handler is None:
              return error.get_response()  # type: ignore
          else:
              return await handler(error)

          This will attempt to find a handler for the error and if fails
          will fall back to the error response.
