Improve error information when paging using page Iterator

[andrueastman]

            var users = new List<User>();

            var response = await GraphServiceClient.Groups[groupId].TransitiveMembers
                .GraphUser
                .GetAsync(x => x.QueryParameters.Select = new[]
                    { "id", "displayName", "mail", "otherMails", "userPrincipalName", "accountEnabled", "proxyAddresses", "officeLocation" });
            var pageIterator = PageIterator<User, UserCollectionResponse>.CreatePageIterator(
                GraphServiceClient, response, (user) => { users.Add(user); return true; });
            await pageIterator.IterateAsync();

            return users;

The problem is that this happens only for one particular group (we use that code on multiple AADs and all works ok, except one particular group within one AAD). I know that the group has members, but I don't actually have access to authorize as the service principal and debug the code (this happens in production). So the problem is, I'm getting an error, but I don't know what it is about, beside it being http status 400.

I was hoping that this would give me the body of the response in the logs (i.e. when doing .ToString() on the ApiException), but looking at the code, it doesn't seem like it.

Hello,

I am still seeing this generic error message "Microsoft.Kiota.Abstractions.ApiException: The server returned an unexpected status code and no error factory is registered for this code: 400. The graph SDK nuget package version being used is 5.18.0
