Is it possible that the "UserId" value returned by CWebServicesManager is empty?

Is it possible that the "UserId" value returned by CWebServicesManager is empty or can be changed by the user?

 CWebServicesManager mgr = new CWebServicesManager();
                    bool isInitialized = mgr.Initialize();

                    if (isInitialized)
                    {
                        try
                        {
                            m_inventorApplication.Login();
                            string userId = "";
                            mgr.GetUserId(ref userId);
                        }
                        catch (Exception ex)
                        {
                            MessageBox.Show(ex.Message);
                        }
                    }

Hi @HideoYamada,

I read your blog on this subject (https://qiita.com/yamarah/items/c7cd1ec7acc6e487d574), but since I don't know Japanese, I translated it from Google Translate.
As far as I understand, if the user is logged in to the autodesk product, there is no possibility of "UserId" being empty. Isn't this true?

I believe it must be true.

Don't forget the codes must be run as Inventor's add-in.
