Gregory Petrosyan created AIRFLOW-581:
-----------------------------------------
Summary: "Recent statuses" widget not working; related SQL
exception on "Chart" page
Key: AIRFLOW-581
URL: https://issues.apache.org/jira/browse/AIRFLOW-581
Project: Apache Airflow
Issue Type: Bug
Affects Versions: Airflow 1.7.1.3
Reporter: Gregory Petrosyan
I am following the quick start (https://airflow.incubator.apache.org/start.html)
After successfully running backfill for `example_bash_operator` from CLI,
"Recent statuses" widget is empty. However, various DAG views for this DAG show
valid data; so the database is not empty.
Additionally, default «Airflow task instance by type» chart, which does
```SQL
SELECT state, COUNT(1) as number FROM task_instance WHERE dag_id LIKE
'example%' GROUP BY state
```
shows an error «SQL execution failed. Details: 'NoneType' object has no
attribute 'get_pandas_df'». This looks related to not working "recent statuses"
widget.
