   Just wanted to chime in here since I had the same exact issue. I found the issue was only present when using the deprecated executor_config format. When I upgraded to using the pod_override with the k8s models my graph view was able to render. So it appears to be due to something in the backward compatibility process. Example:
   
   **Broken...**
   ```
   PythonOperator(
       task_id=f"sync_{table_name}",
       python_callable=sync_table,
       provide_context=True,
       op_kwargs={"table_name": table_name},
       executor_config={"KubernetesExecutor": {"request_cpu": "1"}},
       retries=5,
       dag=dag,
   )
   ```
   
   
   **Works!**
   ```
   PythonOperator(
       task_id=f"sync_{table_name}",
       python_callable=sync_table,
       provide_context=True,
       op_kwargs={"table_name": table_name},
       executor_config={
           "pod_override": k8s.V1Pod(
               spec=k8s.V1PodSpec(
                   containers=[
                       k8s.V1Container(
                           name="base",
                           resources=k8s.V1ResourceRequirements(requests={"cpu": "1"}),
                       )
                   ]
               )
           )
       },
       retries=5,
       dag=dag,
   )
   ```
