error
Key: AIRFLOW-2788
URL: https://issues.apache.org/jira/browse/AIRFLOW-2788
Project: Apache Airflow
Issue Type: Bug
Components: utils
Affects Versions: 1.9.0
Environment: macos
Reporter: Eran Levy
Assignee: Eran Levy
Fix For: 1.9.0
Im using airflow 1.9.0 on macos, installed using:
pip install apache-airflow
Configured MySQL 5.7 as my metadata backend database server with pymysql.
airflow initdb bootstrapped the database tables successfully.
Error raised only when used mysql - didnt encounter any error while using the
default SQLite database.
Reproduce steps:
1. Run the airflow webserver
2. Open the UI and click "DAGs" in the top navigation menu
3. Click one of the available dags - example dags or your own
4. You will see an "Ooops" page with the following error:
