IllegalArgumentException: имя поля не существует в объекте при выполнении миграции

Я пытаюсь перенести Realm с версии 0 на 1. У меня есть POJO следующим образом:

@Parcel(implementations = {OrganizerRealmProxy.class},
        value = Parcel.Serialization.BEAN,
        analyze = {Organizer.class})
public class Organizer extends RealmObject {

    @PrimaryKey
    private long Id;
    private String email;
    private String displayName;
    private Boolean self;
    ...


}

И в методе миграции я делаю:

RealmObjectSchema organizerSchema = schema.create("Organizer")
                    .addPrimaryKey("Id")
                    .addField("email", String.class)
                    .addField("displayName", String.class)
                    .addField("self", Boolean.class);

Но я получаю исключение:

ОБНОВИТЬ

После использования addField("id", String.class, FieldAttribute.PRIMARY_KEY, FieldAttribute.REQUIRED) вместо addPrimaryKey я начал получать другое исключение:

io.realm.exceptions.RealmMigrationNeededException: Field 'id' does
support null values in the existing Realm file. Remove @Required or 
@PrimaryKey from field 'id' or migrate using 
io.realm.internal.Table.convertColumnToNotNullable()

Код моего класса Complete Migration выглядит следующим образом:

public class RealmMigration implements io.realm.RealmMigration {
    @Override
    public void migrate(DynamicRealm dynamicRealm, long oldVersion, long newVersion) {

        // DynamicRealm exposes an editable schema
        RealmSchema schema = dynamicRealm.getSchema();
