[GitHub] [airflow] SamWheating commented on issue #13768: I set "start_date" as datetime but anyway I got this error

   > 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.
