Unable to view logs in Airflow 2.4.0

Hi All,
in Airflow 2.4.0 - newly setup system - the logs are not shown in the Airflow UI. Kubernetes executor is used for running the tasks.
The pod starts and immediately stops without any logs. the job is marked as success.
Any clues?

logs and configuration are attached below. thanks.
