Exception "Dangling name: extfq0cslxr_adminschemakey" when updating schema extension values

Describe the bug

I referred to the Microsoft documentation(https://learn.microsoft.com/en-us/graph/extensibility-overview?tabs=java) on schema extensions and tried using the provided code to update schema extension values directly. However, I encountered an exception with the message "Dangling name: extfq0cslxr_adminschemakey".

I am seeking a way to improve performance and avoid the exception by using direct filters to retrieve and update schema extension values.

Expected behavior

The schema extension values should be updated without any exceptions.

How to reproduce

Steps to Reproduce:

• Use the Microsoft Graph dependency with version 6.x.
• Refer to the following document to update the schema extension value on a particular group.
  -Use the provided Java code:

GraphServiceClient graphClient = new GraphServiceClient(requestAdapter);

User user = new User();
HashMap<String, Object> additionalData = new HashMap<String, Object>();
extkmpdyld2GraphLearnCourses = new ();
extkmpdyld2GraphLearnCourses.setCourseType("Instructor-led");
extkmpdyld2GraphLearnCourses.setCourseId(null);
additionalData.put("extkmpdyld2_graphLearnCourses", extkmpdyld2GraphLearnCourses);
user.setAdditionalData(additionalData);
User result = graphClient.users().byUserId("{user-id}").patch(user);

Encounter the following exception message while updating the value: "Dangling name: extfq0cqexr_adminschema".

SDK Version

6.10.0

Latest version known to work for scenario above?

5.x

Known Workarounds

Below Code works :
GraphServiceClient graphClient = GraphClientBuilder.getGraphClient();
       Map<String, UntypedNode> map = new HashMap<>();
       Map<String, Object> additionalData = new HashMap<>();
       UntypedString productId = new UntypedString(group.getProductId());
       UntypedString productAdminGroupId = new UntypedString("xxx-xx");
       UntypedString linkedOrgGroupId = new UntypedString("xxx-xx-xxx);
       UntypedBoolean adminGroup = new UntypedBoolean(true);
       map.put("productId", productId);
       map.put("productAdminGroupId", productAdminGroupId);
       map.put("linkedOrgGroupId", linkedOrgGroupId);
       map.put("adminGroup", adminGroup);
       UntypedObject untypedObject = new UntypedObject(map);
       additionalData.put(DIConstants.GROUP_ADDITIONAL_ATTRIBUTES_SCHEMA_KEY, untypedObject);
       updateGroup.setAdditionalData(additionalData);
       graphClient.groups().byGroupId(groupId).patch(updateGroup);

### Configuration

_No response_

### Other information

I'm currently using the workaround code,but the following code is impacting the performance of APIs.So i'm looking for the direct filters from graph SDK

まず、Microsoft のドキュメントにあるスキーマ拡張の更新を Microsoft Graph SDK 6.10.0 で再現し、報告されている 5.x の動作と比較します。直接更新で additionalData がどのようにシリアル化されるか、また “Dangling name” 例外がどこで発生するかを追跡し、その後、ドキュメントに記載された更新が UntypedNode の回避策なしで成功することを確認します。
