Airflow “U上的气流成功回调函数因”失败；收到一个学期的通知。“终止子流程”；

我们的on_success回调函数在完成之前被气流异常终止。但这项任务被标记为成功。 我们的on_success回调函数是一个简单的python函数，没有多线程。我复制了相同的错误，用sleep替换了我们的实际逻辑（10）。 请参考以下代码重新创建问题

如果我把睡眠时间减少到2，那么它就会成功完成。如果我的on_success功能需要2秒以上，则气流会中止该功能

感谢任何人的帮助

气流版本：v1.10.0

代码：

我知道这是个老问题，但你解决问题了吗？我和另一个运营商有同样的问题。你能解决这个问题吗？我也面临着这个问题。谢谢
