SDK returns site `name` inconsistently: sometimes same as `displayName` instead of correct value and sometimes the correct value

Beginnen Sie am Einstiegspunkt graphClient.sites().get() und vergleichen Sie, wie das SDK die beiden erfassten Microsoft Graph-Antworten darstellt, einschließlich name und isPersonalSite. Verwenden Sie die gemeldeten Listen- und Suchantworten, um die erwartete Konsistenz festzulegen; erledigt ist die Aufgabe, wenn das SDK stabile Werte für beide Felder bereitstellt oder eine Einschränkung im Upstream eindeutig dokumentiert.

Describe the bug

Doing different site lists returns different values in the name field.

Doing a search limited to a smaller set of sites returns the correct / expected value in the name field.

Doing a list of all sites returns the displayName in the name field.

Expected behavior

The SDK should return values in the name field consistently.

How to reproduce

1. Return sites using this code:

graphClient.sites().get()

The return value in the MSGraph API response is:

        "hostname": "mytenant.sharepoint.com"
      },
      "root": {}
    }
  ]
}

2. Return just one of the above sites, example here is the one with "Many" in the display name (Kotlin):

graphClient.sites().get {
  it.queryParameters.search = "Many"
}

and the return value in the MSGraph API response is now:

{
  "@odata.context": "https://graph.microsoft.com/v1.0/$metadata#sites",
  "value": [
    {
      "createdDateTime": "2025-03-31T16:03:30Z",
      "description": "Test Site Many Names Description",
      "id": "mytenant.sharepoint.com,d0536e25-0c9c-4a9c-b879-cefdc46dc82d,9f7ed8fa-4175-4a6c-80ae-2e19f19f5948",
      "lastModifiedDateTime": "2025-03-31T16:03:38Z",
      "name": "TestSiteManyNames",
      "webUrl": "https://mytenant.sharepoint.com/sites/TestSiteManyNames",
      "displayName": "Test Site Many Names Site Info Name",
      "root": {},
      "siteCollection": {
        "hostname": "mytenant.sharepoint.com"
      }
    }
  ]
}

Note the difference in the Name fields. The first response contains "name": "Test Site Many Names Site Info Name" while the second response contains "name": "TestSiteManyNames".

Note also that the second response does not contain isPersonalSite: false (even if isPersonalSite is requested explicitly via $select).
