andormarkus opened a new issue #16013:
URL: https://github.com/apache/airflow/issues/16013
Apache Airflow version: 2.0.2
Helm chart version: 1.0.0
Kubernetes version: 1.20
**What happened**:
Airflow airflow-cleanup cronjob is failing with the error below. When I run
the same command form the webserver or scheduler pod I got the same error.
```bash
> airflow@airflow-webserver-7f9f7954c-p9vv9:/opt/airflow$ airflow kubernetes
cleanup-pods --namespace airflow
