我正在创建一个工人，将执行数据库操作及时。当我定义我的private readonly validationRuleRepository: ValidationRulesRepository,时，它似乎没有注册cron。
ValidationRulesRepository的作用域也是Scope.DEFAULT。

@Injectable({ scope: Scope.DEFAULT })
export class RulesCleanupWorker {
    private readonly logger: Logger = new Logger(RulesCleanupWorker.name);

    public constructor(
        private readonly validationRuleRepository: ValidationRulesRepository,
    ) { }

    @Cron(CronExpression.EVERY_30_SECONDS)
    public async handleCron(): Promise<void> {
        this.logger.debug('Starting to delete version 00 validation rules');
        // await this.validationRuleRepository.deleteVersion00Rules();
        this.logger.debug('ended clean up activity');
    }
}

cronjob不执行，也未注册。我在日志中看到以下警告：
