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

Beginnen Sie damit, die Aktualisierung der Schemaerweiterung aus der Microsoft-Dokumentation mit Microsoft Graph SDK 6.10.0 nachzustellen und sie mit dem gemeldeten funktionierenden Verhalten der 5.x-Version zu vergleichen. Verfolgen Sie, wie additionalData für die direkte Aktualisierung serialisiert wird und wo die Ausnahme „Dangling name“ ausgelöst wird, und überprüfen Sie anschließend, dass die dokumentierte Aktualisierung ohne den UntypedNode-Workaround erfolgreich ist.
