        Global.SaveError(ex);
        TempData["Message"] = ex.ToString();

    }

    return Json(new Item {  Name = filePaths });
}

---Generate pdf method

 public byte[] GenerateFormPdf(OnlineFormModel model)
  {
    try
      {
          var data= _generatepdf.GetPDF(model.HtmlData);

          return data;

      }
        catch (Exception ex)
      {
        Global.SaveError(ex);
        TempData["Message"] = ex.ToString();
      }

      return null;
  }


Above error is getting on 

var data= _generatepdf.GetPDF(model.HtmlData);

Getpdf is pre defined function of Wkhtmltopdf
