Microsoft graph: ICalUid is returned null when loading selected fields in calendarView

We are using the CalendarView endpoint to get the list of meetings from the calendar.

If we specify $select to get limited fields the iCalUid is returned null, even though we specify iCalUid in $select.

Following is the sample request that returns null iCalUid

https://graph.microsoft.com/v1.0/me/calendar/calendarView?startDateTime=2020-04-09T04:00:00.000Z&endDateTime=2020-05-01T04:00:00.000Z&$top=100&$orderby=start/dateTime%20asc&$select=id,subject,iCalUId

If we do the same call without $select filter it works fine and returns proper iCalUid.

This problem only happens with one particular tenant the above scenario is working fine for hundreds of other tenants.

Following are some details to debug the session

client-request-id: 9faa4f1a-4cbc-4467-8e1c-15ac34e6a2ae

I tried repro the issue with the above Graph API request, but it works for me. I can get the iCalUid.

You can give a try with Microsoft Graph Explorer/POSTMAN for the given tenant and see if you can still repro the issue or also you can limit the smaller number of items. If you can repro the issue, i would suggest you to check these items using tools like MFCMAPI/EWSEditor or use Microsoft CalCheck utility to see they're in good shape and fix the issue.
