[GitHub] [airflow] lgwacker commented on issue #13799: Scheduler crashes when unpausing some dags with: TypeError: '>' not supported between instances of 'NoneType' and 'int'

   I think I found out what was causing this. If you had a DAG with tasks on running state before the upgrade, when you turn those on after upgrading, this error happens.
   
   Try clearing the whole dag run before unpausing.
