   done that but doesn't seem like much changed:
   ```
   $ cat 
/home/airflow/.local/lib/python3.10/site-packages/airflow/providers/cncf/kubernetes/executors/kubernetes_executor_utils.py
 | grep Unknown
                   self.log.exception("Unknown error in KubernetesJobWatcher. 
Failing", exc_info=True)
   ```
   
   here's what it says with that change:
   
   ```
