     * @usageNotes
     * The constructor arguments define the HTTP response.
     * - The `message` argument defines the JSON response body.
     * - The `error` argument defines the HTTP Status Code.
     *
     * By default, the JSON response body contains two properties:
     * - `statusCode`: defaults to the Http Status Code provided in the `error` argument
     * - `message`: the string `'Gateway Timeout'` by default; override this by supplying
     * a string in the `message` parameter.
     *
     * To override the entire JSON response body, pass an object.  Nest will serialize
     * the object and return it as the JSON response body.
     *
     * The `error` argument is required, and should be a valid HTTP status code.
     * Best practice is to use the `HttpStatus` enum imported from `nestjs/common`.
     *
     * @param message string or object describing the error condition.
     * @param error HTTP response status code
