> Q2. why this large error? i believe its related to the fact that this is new
> airflow instance where no DAGs/tasks have run yet so it is expecting some
> execution_date value but none is there. Confirmed this as creating a new 3
> letter pool name still gives the large error after clicking on the name of
> the created pool
> Q3. why limit to 50 length at all?
