> We've got airflow installation with hundreds of DAGs and thousands of tasks.
> During upgrade (1.8.2 -> 1.9.0) we've got following error.
> After analyzing stacktrace i've found that it's most likely caused by None value in 'fileloc' field of Dag column. I checked database and indeed we've got one record with such value:
>  
>  
> {code:java}
> SELECT COUNT(*) FROM dag WHERE fileloc IS NULL;
> 1
> SELECT COUNT(*) FROM dag;
> 343
> {code}
