 * for HTTP clients, ensuring consistent capability like adding default headers

     * to automatically set the proper multipart/form-data boundary.

     * If the response indicates failure (non-OK status), it maps the response status to a

     *
     * @returns A response interceptor that transforms errors into custom exceptions.

     * httpClient.interceptors.response.use(HttpInterceptors.transformErrors());

     * - `HTTPAuthorizationError` (401)
     * - `HTTPForbiddenError` (403)
     * - `HTTPNotFoundError` (404)
     * - `HTTPTimeoutError` (408)
     * - `HTTPInternalServerError` (500)
     * - 'HTTPError' (default)
