Hi all, I am using a user API : https://graph.microsoft.com/v1.0/users?$select=country,companyName,city&$expand=contacts($select=jobTitle)
OR API : https://graph.microsoft.com/v1.0/users?$select=country,companyName,city&$expand=contacts getting

 "error": {
        "code": "InternalServerError",
        "message": "Error processing response from backend service."

I am attaching a screenshot of Postman on which I am facing the issue.

  1. Please check if there is an error in the URL or query parameters.
  2. Why I am facing this issue and how can I fix it?
  3. Also when I am using API: https://graph.microsoft.com/v1.0/users?$select=country,companyName,city&$expand=extensions it is working fine and getting 200 ok status.

Could anyone help me with this?

    Hi Vinay Sharma, Thanks for reaching out. There is nothing wrong either with the API or the query. Contacts property is only available for the users for whom the mailboxes are configured. Since you are using this query on all the users, there might be some users for which mailbox is not configured. Maybe you can try running the following query (There might be some users in the tenant for which mailbox is not setup like service accounts or conference rooms) https://graph.microsoft.com/v1.0/users/{user-id}/contacts In case it is not set up you will get the following error

    If you will run the following query on beta endpoint. you will get to know that this feature will be removed in upcoming releases, and you will get the error message as in screenshot below. https://graph.microsoft.com/beta/users/{user-id}?$expand=contacts
