error 404 user id 'X' not found but the user exists

Question

Hey,
I work with Microsoft Graph API specifically on Microsoft Teams, my goal is to bring the apps that a team user uses.

First I use an API that brings the groups that are team with the request:
https://graph.microsoft.com/v1.0//groups?$filter=resourceProvisioningOptions/Any(x:x eq 'Team')

After that, I take the ID of a group that is a team and I bring all its users with the request:
https://graph.microsoft.com/v1.0/groups/{group-id}/members.

And finally to fetch the apps for each user, I use the request:
https://graph.microsoft.com/v1.0/users/{user-id}/teamwork/installedApps

The problem is that there are certain users that when I make the last request I get the error:
"message": "User Id {user-id} not found."

Although if I use the similar request:
https://graph.microsoft.com/v1.0/users/{user-id}
I do get information about that user.

Would appreciate help!

Answer 1

We tried to repro the issue by running below API to get list of installed apps for user and got desired result as below:

Please reverify the {user-id} , if you are using the right one.
As an alternative, could you please try with {user-principal-name} instead of {user-id} and let us know the results if it helps.

Thanks,

Prasad Das

Hi @Niv Zetuni

Only administrators can call this api endpoint, and if you are using auth code flow or ROPC flow to obtain a user token, then you need to use global administrator login verification.

Another approach is to grant TeamsAppInstallation.ReadForUser.All application permissions, and then use the client credential flow to get an application token, which you can also correctly call that endpoint.

Answer 3

Hi @Niv Zetuni ,

Based on my test List apps installed for user works with delegated and application permissions and with the request-id the internal error message returned is InvalidRequiredParameter-azureSubscriptionId cannot be null or empty, this would need further analysis.

Also it appears the issue is with the specific user or tenant, request you to open a support ticket with Microsoft and a specialized support engineer will help you better on this.
You can raise technical support request from
https://portal.azure.com/#view/Microsoft_Azure_Support/HelpAndSupportBlade/~/overview or https://admin.microsoft.com/#/support/requests.

Hope this helps.
