      "value": "Steeltoe is an open source project that provides a collection of libraries that helps users build cloud-native applications. In Steeltoe.Discovery.Eureka prior to versions 4.2.0 and 3.4.0, `DataCenterInfo.FromJson` throws `ArgumentException` for any `name` value other than `\"MyOwn\"` or `\"Amazon\"`, despite the Java Eureka specification defining a third valid value: `\"Netflix\"`. The exception propagates through the entire registry deserialization chain and is swallowed by the periodic cache refresh task, leaving the local service registry permanently empty or stale. Versions 4.2.0 and 3.4.0 patch the issue. If an immediate upgrade is not possible, remove any registrations using unsupported `DataCenterInfo.name` values from the registry. In mixed Java/Spring and Steeltoe environments, audit for the `Netflix` data center type before deploying Steeltoe Eureka clients."

      "value": "Steeltoe es un proyecto de código abierto que proporciona una colección de bibliotecas que ayuda a los usuarios a construir aplicaciones nativas de la nube. En Steeltoe.Discovery.Eureka, antes de las versiones 4.2.0 y 3.4.0, “DataCenterInfo.FromJson” lanza “ArgumentException” para cualquier valor de “name” que no sea ’MyOwn’ o ’Amazon’, a pesar de que la especificación Java Eureka define un tercer valor válido: ’Netflix’. La excepción se propaga a través de toda la cadena de deserialización del registro y es absorbida por la tarea periódica de actualización de la caché, dejando el registro de servicio local permanentemente vacío u obsoleto. Las versiones 4.2.0 y 3.4.0 parchean el problema. Si una actualización inmediata no es posible, elimine del registro cualquier registro que utilice valores de “DataCenterInfo.name” no compatibles. En entornos mixtos de Java/Spring y Steeltoe, audite el tipo de centro de datos ’Netflix’ antes de implementar clientes Steeltoe Eureka."
