Some Objectify question

gistfile1.java

@Entity
public class Person {
  @Id
  private Long id; 
  
  @Index
  boolean archived;
 
  PersonInfo personInfo;
}
 

public class PersonInfo  {
    
    @Container
    Person person;
    
    @Index(IfNotArchivedEmbed.class)
    String name;
    
    @Index(IfNotArchivedEmbed.class) 
    String surname;
   
   protected static class IfNotArchivedEmbed extends PojoIf<PersonInfo> {
        @Override
        public boolean matchesPojo(PersonInfo   pojo) {
            return !pojo.person.isArchived();
        }
    }
 
}

Problem: in matchesPojo method in IfNotArchivedEmbed class I get a NullPointer Exception when trying to obtain person instance. It seems @container field is not populated when accessed matchesPojo method on index,
