Has anyone been able to create a user with the DNN 7 WepAPIFramework? I'm getting an "There was an error generating the XML document" exception in my call to UserController.CreateUser(ref user);

My helper function to create the user is a subclass of DnnApiController and I do have other .DnnApiController methods working correctly.

Here's my CreateUser function that is failing.

private void CreateUser()
{
UserInfo.Membership.Approved = true;
var user = UserInfo;
CreateStatus = UserController.CreateUser(ref user);
return;

if (CreateStatus == UserCreateStatus.Success)
{

////Assocate alternate Login with User and proceed with Login
//if (!String.IsNullOrEmpty(AuthenticationType))
//{
// AuthenticationController.AddUserAuthentication(UserInfo.UserID, AuthenticationType, UserToken);
//}


// _AccountRequest.Message = UserController.CompleteUserCreation(CreateStatus, user, true, IsRegister);
// create psari subscriber
SubscriberFactory sf = new SubscriberFactory();
Subscriber s = sf.CreateSubscriber();
s.SubcriberLevel = (int)SubscriberFactory.SubscriberLevel.Guest;
s.CityId = 0;
s.Email = _AccountRequest.Email;
// save subscriber to get subscriber id
s.Save();
_AccountRequest.SubscriberId = s.SubscriberId;
_AccountRequest.StatusCode = 0;
}
else
{
_AccountRequest.Message = UserController.GetUserCreateStatus(CreateStatus);
}
}

I've been able to trace the error to a call to this function in the DNN kernel:

private void AddDNNUserRole(UserRoleInfo userRole)

in the

public class DNNRoleProvider : RoleProvider

It seems that the code is excepting out one of the following class level variable instnatiation, since I never enter the AddDNNUserRole function.

private static readonly ILog Logger = LoggerSource.Instance.GetLogger(typeof (DNNRoleProvider));

private readonly DataProvider dataProvider = DataProvider.Instance();

Any suggestions would be greatly appreciated.
