我想在每个月的第三个星期日触发触发器。在 cron 表达式中,我使用了 cron="0 0 23 ? * 1#3" 但它给了我异常

这是我正在尝试的代码
@Scheduled(cron="0 0 23 ? * 1#3") // Fire at 11 PM on the third sunday of every month
public void sendReportNotCreatedNotificationToStudent() throws Exception{
scheduleNotificationIntf.sendScheduleNotificationToStudent("createReportRemainder.html");
}
请任何人告诉这个错误。我怎样才能实现这个 Cron 表达式。
