Failed to execute MS Graph backend request GetGroupInternalApiRequest

Question

In my project, there is a requirement to create Site Collection with Office 365 group, so I have used following method CreateUnifiedGroup of OfficeDevPnP.Core.Framework.Graph namespace. Here is the sample code that I have used:

var title = "Dev POC Test ";
var description = "Some description of site goes here";
var group = UnifiedGroupsUtility.CreateUnifiedGroup(title, description,
                                                Regex.Replace(title, @"[^0-9a-zA-Z:,]+", ""), accessToken,
                                                groupLogo: null, isPrivate: true, createTeam: true, retryCount: 10, delay: 500);

Console.WriteLine(group.SiteUrl);

Well, previously above code was working fine but now it is giving rare error message at function calling CreateUnifiedGroup like below:

System.ApplicationException: Exception while invoking endpoint https://graph.microsoft.com/v1.0/groups/9d099dfd-1028-4f55-9dfb-fc4863aabeaf/team. ---> System.Web.HttpException: {

  }
}

I understand this has something to do with Microsoft's server, but has anyone encountered such error before? Can we do something to resolve this issue?

Any help would be much appreciated!

Answer 1

I can reproduce this error, it was failed during the stage of Team provision. In fact the group has been created, you can check it through the admin centre.

This error also occurs on PowerShell cmdlets New-PnPUnifiedGroup, I believe it's the same cause and come from below limit:

• https://docs.microsoft.com/en-us/graph/teams-create-group-and-team (step 4, you may have to wait as long as 15 minutes before you can create the team)

A workaround is to create a group without CreateTeam parameter, after that invoke teams creation from the graph directly. Or you can directly increase the delay time.

You can directly send a request to create a team via HTTP client as the access token is already here.
