Web UI中的Apache Airflow“不允许过早的日期时间”

Question

在/admin/taskinstance/下的Airflow的Web UI中，我试图按需要datetime参数的执行日期进行过滤。甚至建议自动添加日历和时间。

点击带有日期时间过滤器的“提交”时出现此错误。

Traceback (most recent call last):
  File "/usr/lib/python3.6/site-packages/sqlalchemy/engine/base.py", line 1116, in _execute_context
    context = constructor(dialect, self, conn, *args)
  File "/usr/lib/python3.6/site-packages/sqlalchemy/engine/default.py", line 649, in _init_compiled
    for key in compiled_params

  File "/usr/lib/python3.6/site-packages/airflow/utils/sqlalchemy.py", line 156, in process_bind_param
    raise ValueError('naive datetime is disallowed')
ValueError: naive datetime is disallowed

上述异常是以下异常的直接原因：

Airflow似乎无法从Web用户界面输入日期格式。 我尝试了我能想到的任何日期时间格式，但仍然没有运气。

有人可以帮忙吗？

这个问题也发生在我身上。我的原因与版本有关。在1.8.1中，可以。在1.10.3中，不是。
