Hi all,

I'm currently getting the error above when running the SaveAndPublishWithStatus method of a content service object. I've stepped through my code in Visual Studio to ensure that none of the items I am passing in the object are null but it is within this Umbraco defined method that the problem is occuring and not my own code. Please see my overall method below:

public void GetCountries(CompressionSoapHeader compressionSoapHeader, ManagedUserHeader managedUserHeader)
{
  StaticDataWebServiceSoapClient webService = null;
  webService = new StaticDataWebServiceSoapClient();
  IContentService contentService = ApplicationContext.Current.Services.ContentService;
  bool success = false;
  try
  {
    //Construct Service Request
    var homePageId = contentService.GetRootContent().ElementAt(0).Id;
    var continentArray = contentService.GetByLevel(3).Where(x => x.ContentType.Alias == "continent");
    foreach (var continent in continentArray)
    {
      var continentId = continent.GetValue<int>("continentId");
      var countries = webService.GetCountryList(ref compressionSoapHeader, ref managedUserHeader, continentId, string.Empty);
      foreach (var country in countries)
      {
        if(country != null){
          var id = country.Id;
          var name = country.Name;
          var notes = country.Notes;
          var description = country.DescriptionData;
          var descConcatenated = String.Empty;
          if (description != null)
          {
            try
            {
              foreach (var desc in description)
              {
                if (desc != null)
                {
                  descConcatenated = descConcatenated + "<br/>" + desc.Notes;
                }
              }
            }
            catch (NullReferenceException e)
            {
              string errorHandler = Request.QueryString["handler"];
              ExceptionUtility.LogException(e, errorHandler);
              Server.ClearError();
            }
          }

          try
          {
            var cs = contentService.CreateContent(country.Name, continentId, "country");
            cs.SetValue("mainPageContent", descConcatenated);
            cs.SetValue("pageTitle", country.Name);
            cs.SetValue("countryNotes", country.Notes);
            cs.SetValue("countryId", country.Id);
            cs.SetValue("continentId", continentId);
            contentService.SaveAndPublishWithStatus(cs);
          }
          catch(Exception e)
          {
            string errorHandler = Request.QueryString["handler"];
            ExceptionUtility.LogException(e, errorHandler);
            Server.ClearError();
          }
        }
      }
    }
  }
  finally
  {
    if (!success && webService != null)
    {
      webService.Abort();
    }
  }
}

Any ideas what could be causing this? According to my error log:

********** 01/05/2014 17:32:29 **********
Exception Type: System.NullReferenceException
