------------------------------------

             Summary: store_serialized_dags raises fatal error for reviewing logs
                 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


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.
