Hello @Elton Tan Jin Rong ,
Thanks for reaching out.
Could you please confirm graph_url being used to get user details by django? If you are using V1.0 which is (https://graph.microsoft.com/v1.0) then you need to switch it to MS Graph beta endpoint https://graph.microsoft.com/beta/ because "employeeId" is only available in MS Graph beta endpoint as of today.
You can check this from Microsoft Graph Explorer as shown below :
Hope this helps.
