Can't select row with uuid predicate:

.... 

public class HumanNameModel extends GenericChildModel<UUID, UUID> {
    public static final String[] HUMAN_NAME_USE = {"usual", "official", "temp", "nickname", "anonymous", "old", "maiden"};

    @QuerySqlField
    private Byte use;
    @QuerySqlField(notNull = true, orderedGroups = {@QuerySqlField.Group(name = "fullname_idx", order = 0)})
    @NotNull
    @Name
    private String family;
    @QuerySqlField(orderedGroups = {@QuerySqlField.Group(name = "fullname_idx", order = 1)})
    @Name
    private String firstName;
    @QuerySqlField(index = true, orderedGroups = {@QuerySqlField.Group(name = "fullname_idx", order = 2)})
    @Name
    private String patronymic;

    public HumanNameModel() {

    }
...
 

CacheConfiguration<UUID, HumanName> cfg = new CacheConfiguration<>(); 
cfg.setBackups(1);
cfg.setAtomicityMode(CacheAtomicityMode.TRANSACTIONAL); 
cfg.setName("HumanName"); 
cfg.setIndexedTypes(AffinityKey.class, HumanNameModel.class); 
ignite.getOrCreateCache(cfg);

 

I think, the problem in "column_size", because if I recreate field "ParentID" from sql (sqlline) it works fine (recreated.png) 

 

PS. Added project to reproduce error (testproj.zip).
