Turn off examples and create your own DAG.  <!-- As minimally and precisely as possible. Keep in mind we do not have access to your cluster or dags. If this is a UI bug, please provide a screenshot of the bug or a link to a youtube video of the bug in action You can include images/screen-casts etc. by drag-dropping the image here. --> **Anything else we need to know**: I haven't seen this last run working ever since I have started using Aiflow <!-- How often does this problem occur? Once? Every time etc? Any relevant logs to include? Put them here inside fenced ``` ``` blocks or inside a foldable details tag if it's long: <details><summary>x.log</summary> lots of stuff </details> --> **Are you willing to submit a PR?**: Sure! but pretty new to Airflow. I believe there should be condition to check for NoneType before accessing its attributes. <!--- This is absolutely not required, but we are happy to guide you in contribution process especially if you already have a good understanding of how to implement the fix. Airflow is a community-managed project and we love to bring new contributors in. Find us in #airflow-how-to-pr on Slack! --> -- This is an automated message from the Apache Git Service.
