Subject [jira] [Commented] (AIRFLOW-1177) variable json deserialize does not work at set defaults
Date Tue, 22 Aug 2017 13:41:00 GMT

Ash Berlin-Taylor commented on AIRFLOW-1177:
--------------------------------------------

I think this issue is larger than just JSON -- {{setdefault}} will die with a similar error
if the object already exists!

> obj has no attribute val, it is the val itself.
> it will throw error like:
> Variable.setdefault("some_key", deserialize_json=True,default=json.dumps(default_dag_variables))
>   File "/usr/local/lib/python2.7/site-packages/airflow/models.py", line 3586, in setdefault
>     return json.loads(obj.val)
> AttributeError: 'unicode' object has no attribute 'val'
