Recurring problem with the "List servicePrincipals" endpoint

Question

When attempting to retrieve the list of service principals within the Microsoft organization, using the 

GET https://graph.microsoft.com/v1.0/servicePrincipals?$select=verifiedPublisher,servicePrincipalType,servicePrincipalNames,samlSingleSignOnSettings,replyUrls,preferredSingleSignOnMode,oauth2PermissionScopes,notificationEmailAddresses,loginUrl,logoutUrl,keyCredentials,signInAudience,info,id,homepage,displayName,tags,notes,disabledByMicrosoftStatus,deletedDateTime,appRoles,passwordCredentials,appRoleAssignmentRequired,appOwnerOrganizationId,tokenEncryptionKeyId,resourceSpecificApplicationPermissions,appId,appDisplayName,description,applicationTemplateId,alternativeNames,addIns,appDescription,accountEnabled&$top=999

endpoint, we encounter the following non-informative error in the response:

{
   "error":{
      "code":"UnknownError",
      "message":"",
      "innerError":{
         "date":"2024-10-28T10:41:32",
         "request-id":"30a45db3-bd23-43b5-a9d4-366483a8948b",
         "client-request-id":"30a45db3-bd23-43b5-a9d4-366483a8948b"
      }
   }
}

We first noticed this problem in early December 2023, but it resolved within a week. Unfortunately, the issue has reappeared, preventing us from delivering our service to customers. As a result, this regression is critical for us.

Is this a known issue? Does anyone else see the same problem?

Hi @Vasyl Artemiuk | Keepit

I just made multiple calls to the API locally and it worked fine for me, so it doesn't look like a known issue. This should be related to your environment, calling the API in your context throws the above error.

I suggest you open a support ticket to report the issue to the Microsoft support team, and the support team can help you pull the background log to find out the cause of the issue.

Hope this helps.
