### Apache Airflow version 3.0.6 ### If "Other Airflow 2 version" selected, which one? _No response_ ### What happened? We are seeing many small issues on AF3 UI, creating this 1 issue to log all those 1. Getting 422 intermittently while checking logs of mapped tasks <img width="3002" height="880" alt="Image" src="https://github.com/user-attachments/assets/bd0b887b-ab3b-422e-8001-7dcaf244564b"; /> ```javascript apiserver INFO: 45.118.158.92:0 - "GET /d5jivb8q/api/v2/dags/kpo_mapped/dagRuns/manual__2025-09-16T09%3A49%3A13.944070%2B00%3A00/taskInstances/cowsay_mapped/NaN HTTP/1.1" 422 Unprocessable Entity apiserver INFO: 45.118.158.92:0 - "GET /d5jivb8q/api/v2/dags/kpo_mapped/dagRuns/manual__2025-09-16T09%3A49%3A13.944070%2B00%3A00/taskInstances/cowsay_mapped/NaN HTTP/1.1" 422 Unprocessable Entity ``` 2. Intermittent issue sometimes tasks are not showing up on grid but after refresh it comes up. https://github.com/user-attachments/assets/cd9cf10a-232a-43c5-b7c5-26273e7e9049 <img width="3456" height="1554" alt="Image" src="https://github.com/user-attachments/assets/79ced803-c4c0-4fc1-85a9-cab91f4ed70a"; /> ### What you think should happen instead? _No response_ ### How to reproduce 1. Create multiple dagruns and intermittently notice tasks are not loaded on grid and comes up after refresh. 2. For mapped task issue, use the below dag ```python from datetime import datetime from airflow.sdk import DAG from airflow.providers.cncf.kubernetes.operators.pod import ( KubernetesPodOperator, ) from airflow.configuration import conf namespace = conf.get("kubernetes_executor", "NAMESPACE") with DAG( dag_id="kpo_mapped", start_date=datetime(1970, 1, 1), schedule=None, tags=["taskmap_skip"] # render_template_as_native_obj=True, ) as dag: KubernetesPodOperator( task_id="cowsay_static", name="cowsay_statc", namespace=namespace, image="docker.io/rancher/cowsay", cmds=["cowsay"], arguments=["moo"], log_events_on_failure=True, ) KubernetesPodOperator.partial( task_id="cowsay_mapped", name="cowsay_mapped", namespace=namespace, image="docker.io/rancher/cowsay", cmds=["cowsay"], log_events_on_failure=True, ).expand(arguments=[["mooooove"], ["cow"], ["get out the way"]]) ``` ### Operating System Linux ### Versions of Apache Airflow Providers _No response_ ### Deployment Other ### Deployment details _No response_ ### Anything else? _No response_ ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://github.com/apache/airflow/blob/main/CODE_OF_CONDUCT.md) -- This is an automated message from the Apache Git Service.
