### Apache Airflow version 3.1.5 ### If "Other Airflow 3 version" selected, which one? _No response_ ### What happened? While testing providers release on 2025-12-30 I noticed that when attempting to create a User in Fab and I miss to set the "Role" field I get a Ooops / HTTP 500 screen: <img width="1152" height="1271" alt="Image" src="https://github.com/user-attachments/assets/0546ad5b-d3ab-4223-b5c3-9195cf273fbe"; /> (see Role field is empty) <img width="1170" height="472" alt="Image" src="https://github.com/user-attachments/assets/cdc5447c-a8c8-4a49-b37d-baebc8d0d481"; /> If a Role is selected it is working.

Same like in Fab as released with Airflow 3.1.5 there should be a validation error generated, not a HTTP 500: <img width="784" height="156" alt="Image" src="https://github.com/user-attachments/assets/d48ec8c6-966e-4ad0-8d75-09db24854317"; /> ### How to reproduce Use Fab apache-airflow-providers-fab==3.1.1rc1 or start on latest main via `breeze start-airflow --python 3.12 --load-example-dags --backend postgres --executor LocalExecutor --answer y --auth-manager FabAuthManager` Log in as admin and go to Security->Users, add a user and miss-out to fill the "Roles" field. ### Operating System Linux ### Versions of Apache Airflow Providers Fab 3.1.1rc1 or latest main ### 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.
