Question

从Airflow 1.9升级到1.10后，我不再能够在Web GUI中看到“任务持续时间”。当我单击“任务持续时间”时，将得到以下回溯：

TypeError: unsupported operand type(s) for +=: 'int' and 'NoneType'

你知道是什么原因造成的吗？

这仅发生在我的旧DAGS上。升级后创建的新DAGS不会出现此问题。

看起来您较旧的记录的行在NULL列上有task_fail.duration。对数据库运行手动查询可能会解决您的问题：UPDATE task_fail SET duration=0 WHERE duration IS NULL-假设您可以更改记录。

为了以防万一，请确保也先锁定备份。
