> Key: AIRFLOW-6578
> URL: https://issues.apache.org/jira/browse/AIRFLOW-6578
> Project: Apache Airflow
> Issue Type: Bug
> Components: core
> Affects Versions: 1.10.7
> Environment: local development
> Reporter: Xiaodong Ye
> Assignee: Xiaodong Ye
> Priority: Major
>
> When I set the configuration "store_serialized_dags" to True, it will raise errors during log checking.
> {quote}File "/Users/christian/anaconda3/envs/airflow/lib/python3.7/site-packages/airflow/models/taskinstance.py", line 1149, in get_template_context if 'tables' in task.params: TypeError: argument of type 'NoneType' is not iterable
> {quote}
> I tried to dump the task instance and found the task's params variable is a dict type (empty dict so far) when the setting "store_serialized_dags" is False, otherwise, it will be None type and causes troubles.
> So I have to hardcode line 1149 from
> if 'tables' in task.params:
> to
> if task.params and 'tables' in task.params:
>
> BTW, I'm new to airflow and to its core, currently, I'm not sure what the tables variable used for and of course its incoming impact.
