Serialization error of objects in Graph v6.1

Serialization of an Graph Drive will lead to an error:

I think because of the Code in Drive:

public void serialize(@Nonnull final SerializationWriter writer) {
        Objects.requireNonNull(writer);
        super.serialize(writer);
        writer.writeCollectionOfObjectValues("bundles", this.getBundles());
        writer.writeStringValue("driveType", this.getDriveType());
        writer.writeCollectionOfObjectValues("following", this.getFollowing());
        writer.writeCollectionOfObjectValues("items", this.getItems());
        writer.writeObjectValue("list", this.getList(), new Parsable[0]);
        writer.writeObjectValue("owner", this.getOwner(), new Parsable[0]);
        writer.writeObjectValue("quota", this.getQuota(), new Parsable[0]);
        writer.writeObjectValue("root", this.getRoot(), new Parsable[0]);
        writer.writeObjectValue("sharePointIds", this.getSharePointIds(), new Parsable[0]);
        writer.writeCollectionOfObjectValues("special", this.getSpecial());
        writer.writeObjectValue("system", this.getSystem(), new Parsable[0]);
    }

There is an owner defined and linked to IdentitySet but in IdentitySet:

public void serialize(@Nonnull final SerializationWriter writer) {
        Objects.requireNonNull(writer);
        writer.writeObjectValue("application", this.getApplication(), new Parsable[0]);
        writer.writeObjectValue("device", this.getDevice(), new Parsable[0]);
        writer.writeStringValue("@odata.type", this.getOdataType());
        writer.writeObjectValue("user", this.getUser(), new Parsable[0]);
        writer.writeAdditionalData(this.getAdditionalData());
    }

There is no "group" -> error

Perhaps there are more missing "IdentitySet" object, but I think at least group is missing

Expected behavior

The serialization works and gives JSON from the Microsoft object

Actual behavior

IllegalStateException at serialization

Steps to reproduce the behavior

Map<String, Object> raw = null;
        try (final SerializationWriter writer = new JsonSerializationWriter()) {
            writer.writeObjectValue("", graphDrive);
            try (final InputStream stream = writer.getSerializedContent()) {
                String json = new String(Compatibility.readAllBytes(stream), StandardCharsets.UTF_8);
                raw = Map.of(GRAPH_DRIVE, json);
            }
        } catch (IOException | RuntimeException e) {
            log.warn("Could not serialize graphDrive: {}", graphDrive, e);
        }

will explode at

writer.writeObjectValue("", graphDrive);

シリアライズ呼び出し箇所の GraphDriveConverter.java と、getRootDrive 周辺の GraphDriveRepositoryTest.java から始め、次にレポートに示されている Drive と IdentitySet の serialize メソッドを調べます。Dangling name: group の失敗を再現し、owner を含む Drive のシリアライズが不完全な JSON ドキュメントなしで完了することを確認します。
