> The traceback suggest that you are using get_previous_start_date in your DAG. We've seen this issue on one of our DAGs as well (when viewing task details from a run with many preceeding runs) and I can confirm we are not using the `get_previous_start_date` in the DAG directly - In our case (as well as the above stack trace) it looks like this is called by the get_attr when rendering the task instance details page. I'll see if I can gather more information on the cause of this issue and provide a simple example DAG. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
