pierrejeambrun opened a new issue, #53878: URL: https://github.com/apache/airflow/issues/53878
### Body As mentioned in https://github.com/apache/airflow/pull/53035 Simply running the following dag and trying to access the graph fails: ``` from __future__ import annotations import datetime from airflow.providers.standard.operators.hitl import ApprovalOperator from airflow.sdk import DAG, task with DAG( dag_id="aip_90_dag", start_date=datetime.datetime(2021, 1, 1), schedule="@daily", ): approve_or_reject = ApprovalOperator( task_id="approve_or_reject", subject="This is subject", body="This is body", ) approve_if_timeout = ApprovalOperator( task_id="approve_if_timeout", subject="This is subject", defaults="Approve", execution_timeout=datetime.timedelta(seconds=1), ) @task def run_after_approve() -> None: pass reject_if_timeout = ApprovalOperator( task_id="reject_if_timeout", subject="This is subject", defaults="Reject", execution_timeout=datetime.timedelta(seconds=1), ) @task def skip_due_to_reject() -> None: pass @task def skip_due_to_upstream_skip() -> None: pass approve_if_timeout >> run_after_approve() reject_if_timeout >> skip_due_to_reject() >> skip_due_to_upstream_skip() ``` There is a short flickering where we can see the graph, and then the page goes blank: <img width="988" height="926" alt="Image" src="https://github.com/user-attachments/assets/6ec9b245-9de7-4978-9408-51d43538aa10"; /> ### Committer - [x] I acknowledge that I am a maintainer/committer of the Apache Airflow project. -- This is an automated message from the Apache Git Service.
