GraphWin32LobApp Query Fails

[chrpai]

In my app, I'm using Microsoft.Graph 5.73.0. I can call graphServiceClient.DeviceAppManagement.MobileApps.GetAsync() just fine but when I try to call graphServiceClient.DeviceAppManagement.MobileApps.GraphWin32LobApp.GetAsync() I get an exception:

No OData route exists that match template ~/singleton/navigation/cast with http verb GET for request /AppLifecycle_2502/StatelessAppMetadataFEService/deviceAppManagement/mobileApps/microsoft.management.services.api.win32LobApp

n my appsettings I have:

"GraphApi": {
"BaseUrl": "https://graph.microsoft.com/v1.0",
"Scopes": [
"user.read",
"DeviceManagementApps.ReadWrite.All",
"GroupMember.Read.All"
]
}

Is this a bug in the SDK? I haven't tried rest API calls yet. I do see this related issue from a year ago. #2307
