         {
                    var relativeUri = navigationManager.Uri;
                    var uri = navigationManager.ToAbsoluteUri(relativeUri);

                    if (firstRender){}

if (QueryHelpers.ParseQuery(uri.Query).TryGetValue("isSessionTimeout", out var tempTimeout))
                    {
                           notification?.ShowError(error);
                           //error = "Session timed out";

                    }
}

              try{

              }

              catch(exception ex){
