Airflow logs and kubernetes pod logs are different - airflow-scheduler

Question

We are running airflow on kubernetes. Though airflow runs the DAGs without any issues but I see the below weird error messages in the airflow logs.
However, when I check the kubernetes pod logs where the DAG is running, it doesnt have any issues and all the tasks in the DAG completed successfully. Any reason why i'm getting the below error messages in the airflow logs? Also all the logs are not printed in the airflow logs though everything is printed without any error messages in kubernetes pod logs.
