Start at src/OpenConext/UserLifecycle/Application/QueryHandler/FindUserInformationQueryHandler.php:37 and trace the GET /api/deprovision/{user} entry point. Compare the handler's declared InformationResponseInterface return type with the returned InformationResponseCollection; done means the endpoint no longer raises this TypeError.
