Sprint-data-Cassandra Map matching with a custom type is completed using "not a fixed object type",

Here is my User Defined Type in casssandra:

  create type app
  (   app_id uuid,
      app_name varchar,
      maker varchar
   );

And my table with a map of such a User DefinedType

 create table device 
 (   device_id timeuuid, 
     apps map<uuid,frozen<app>>,

     primary key (device_id) 
);

Its mapping in Java

@Table("device")
public class Device {

   @PrimaryKey
   @Column("device_id")
   private UUID device_id;


   @Column("apps")
   private Map<UUID, App> apps;

}

and

@UserDefinedType
public class App {

   @Column("app_id")
   private UUID app_id;

   @Column("app_name")
   private String app_name;

   @Column("maker")
   private String maker;

}

Now using the standard Sprind-data-cassandra CrudRepository:

public interface DeviceRepository extends CrudRepository<Device, UUID>{

When I try to keep it as such

    Device st1 = new Device();
    st1.setDevice_id(MyUtils.getRandomTimestampUUID());

    /** Apps **/

    App c1 = new App();
    c1.setApp_id(MyUtils.getRandomTimestampUUID());
    c1.setMaker("Maker of game 1");
    c1.setApp_name("game 1");

    App c2 = new App();
    c2.setApp_id(MyUtils.getRandomTimestampUUID());
    c2.setMaker("Maker of game 2");
    c2.setApp_name("game 2");

    Map<UUID, App> apps = new LinkedHashMap<UUID, App>();
    apps.put(MyUtils.getRandomTimestampUUID(), c1);
    apps.put(MyUtils.getRandomTimestampUUID(), c2);

    st1.setApps(apps);

    _deviceRepository.save(st1);

I get this exception:

 java.lang.IllegalArgumentException: Target bean of type java.util.LinkedHashMap is not of type of the persistent entity (com.pfellwock.cassandra.type.App)!

Currentlly spring "map" . , . Collections [app] [interface java.util.Map] [Device].

, , ​​ "@CassandraType" (type = Name.MAP, userTypeName = "address", typeArguments = {Name.TEXT, Name.CUSTOM}) "

. * typeArguments CUSTOM.
