     * @usageNotes
     * The constructor arguments define the response and the HTTP response status code.
     * - The `response` argument (required) defines the JSON response body. alternatively, it can also be
     *  an error object that is used to define an error [cause](https://nodejs.org/en/blog/release/v16.9.0/#error-cause).
     * - The `status` argument (required) defines the HTTP Status Code.
     * - The `options` argument (optional) defines additional error options. Currently, it supports the `cause` attribute,
     *  and can be used as an alternative way to specify the error cause: `const error = new HttpException('description', 400, { cause: new Error() });`
     *
     * By default, the JSON response body contains two properties:
     * - `statusCode`: the Http Status Code.
     * - `message`: a short description of the HTTP error by default; override this
     * by supplying a string in the `response` parameter.
     *
     * To override the entire JSON response body, pass an object to the `createBody`
     * method. Nest will serialize the object and return it as the JSON response body.
     *
     * The `status` argument is required, and should be a valid HTTP status code.
     * Best practice is to use the `HttpStatus` enum imported from `nestjs/common`.
     *
     * @param response string, object describing the error condition or the error cause.
     * @param status HTTP response status code.
     * @param options An object used to add an error cause.
