> `airflow initdb` crashes when there is a dag in dag folder that has owner set
> to None. It crashes with the following error:

>
> This command which sole role is to initialize metadata database lies on the
> critical path of any Airflow deployment. Having bad dag in dag folder should
> not lead to the failure of this command.
