 * @description
 * All errors thrown in the Vendure server must use or extend this error class. This allows the
 * error message to be translated before being served to the client.
 *
 * The error messages should be provided in the form of a string key which corresponds to
 * a key defined in the `i18n/messages/<languageCode>.json` files.
 *
 * Note that this class should not be directly used in code, but should be extended by
 * a more specific Error class.
