Unable to retrieve JSON values from response

[craig-blowfield]

Describe the bug

I am trying to retrieve a workbooks range values but the response object values are empty.

The response (WorkbookRange) contains the basic details of the range such as address and row count, but I can't get the values out.

I am not actually sure how you are meant to retrieve values from properties of type JSON? as I can't find any documentation on this other than some relating to Kiota.

Expected behavior

Returns the row/cell values for the given named range

How to reproduce

var scheduleInformationRange = await graphClient.Drives[workbookDriveItem.ParentReference.DriveId].Items[workbookDriveItem.Id].Workbook.Names["NAMED_RANGE"].Range.GetAsync();

var serializedJsonString = KiotaJsonSerializer.SerializeAsString(scheduleInformationRange.Text);
