Progmatically creating documents Kentico 9

Question

I've to create a new document in the back end but can not find any useful information on how to do this in Kentico 9.

So far I've got

 UserInfo user = UserInfoProvider.GetUserInfo("administrator");

// Creates a tree provider instance using administrator context
TreeProvider tree = new TreeProvider(user);

// Prepare parameters
string siteName = CMS.SiteProvider.SiteContext.CurrentSiteName;
string aliasPath = "/News";
string culture = "en-GB";
bool combineWithDefaultCulture = false;
string classNames = TreeProvider.ALL_CLASSNAMES;
string where = null;
string orderBy = null;
int maxRelativeLevel = -1;
bool selectOnlyPublished = false;
string columns = null;

// Get the example folder
TreeNode parentNode = DocumentHelper.GetDocument(siteName, aliasPath, culture, combineWithDefaultCulture, classNames, where, orderBy, maxRelativeLevel, selectOnlyPublished, columns, tree);

if (parentNode != null)
{
  // Create a new node
  TreeNode node = TreeNode.New("CMS.News", tree);

  // Set the required document properties
  node.DocumentName = "Test";
  node.DocumentCulture = "en-GB";

  // Insert the document
  try
  {
    DocumentHelper.InsertDocument(node, parentNode, tree);
  }
  catch (Exception ex)
  {
    EventLogProvider.LogException("Create New News", "EXCEPTION", ex);
  }
}

This however throws an error:

Message: [WebFarmTaskManager.CanCreateTask]: Task type 'DICTIONARYCOMMAND' is not supported. The task needs to be registered with WebFarmHelper.RegisterTask method.

Has anyone had experience with doing this in Kentico 9?

Sorry, may be my two cents comes too late but I solved the same issue invoking the following initialization method not mentioned on Kentico docs:

CMS.DataEngine.CMSApplication.Init();
