------------------------------------
Summary: ValueError from flask-admin causing Charts feature to break
Key: AIRFLOW-2257
URL: https://issues.apache.org/jira/browse/AIRFLOW-2257
Project: Apache Airflow
Issue Type: Bug
Components: dependencies, ui
Affects Versions: 1.9.0
Reporter: Brian Sloan
Using Airflow 1.9 and RDS PostgreSQL for the metadata database.
This bug may be related to this flask-admin / sqlalchemy issue: https://github.com/flask-admin/flask-admin/issues/1588
To reproduce, go to "Data Profiling –> Charts" and click the Edit icon to edit any chart. I get an HTTP 500 with this traceback:
{code:java}
