Graph Explorer shows data for places but used in Graph demo app undefined is returned

Jon Kelley 20 Reputation points

I am using the Graph Explorer tool and when I use the endpoint of$top=999

I can see the one record I have in my test tenant.

When I use the demo app from this tutorial I get back undefined.

The other APIs seem to work fine like /me or /me/calendarview or /me/getSchedule

Just this one for the room data returns undefined but it works in the Graph Explorer.

FWIW - I can get the availability of the room using the email for the room as part of the /me/calendar/getSchedule call.

    Hi @Jon Kelley

    List Places requires Place.Read.All permission. Please ensure the token generated has this permission before running this Graph API. You can decode the token using and check permissions in your token.

    Please note: Graph explorer, an Enterprise application, uses user signIn permission which is delegated Permission.

    Hope this helps.
