Site description field is always null

Describe the bug

I am trying to obtain the site description using the Graph SDK. However, even though the Graph Explorer shows that the description value is returned, in the SDK the description is always null.

One possible difference is that I am using Azure Identity credentials with a client certificate credential to configure authentication for the SDK. Also tried a client secret credential with the same result.

Expected behavior

The description field should be available.

How to reproduce

Create a site in Sharepoint with a description.

Try to retrieve the description via the Graph Explorer. It works.

Try to retrieve the description via the SDK. It does not work. Debug logs at the HTTP level shows that the odata response does not contain the description field.

For some reason the return value of the Graph Explorer is different than the return value of the SDK, for the exact same API request 👎 .

Other information

No response

No source file or test is named. Reproduce the SharePoint site-description retrieval with SDK 6.33.0, using the Graph Explorer result and HTTP-level SDK response as the comparison points. Done means the SDK response includes the site's description field for the same request.
