Override val descriptor: SerialDescriptor = surrogateSerializer. Private val surrogateSerializer = rializer(tSerializer) for "Error" data: T? = exceptionMessage: String? = null The annotation is not necessary, but it avoids serializing "data = null" to view the data from the database public void view(String name) throws. ) : KSerializer> class ServiceResultSurrogate( If singleton class is Serializable, you can serialize the singleton instance.
