Display error message if Load failed in pdfviewer

[Hafiz]

Hi,

It is possible to display error message return by Load in pdfviewer controller below when 'document' does not exist?
Currently nothing is display on browser. I'm using version (19.2.0.56) as my license expired.

        [HttpPost("Load")]
        [Microsoft.AspNetCore.Cors.EnableCors("MyPolicy")]
        [Route("[controller]/Load")]
        public IActionResult Load([FromBody] Dictionary<string, string> jsonData)
        {
            PdfRenderer pdfviewer = new PdfRenderer(_cache);
            PdfRenderer.ReferencePath = _hostingEnvironment.WebRootPath + @"\";
            if (jsonData.ContainsKey("document"))
            {
                object jsonResult = pdfviewer.Load(jsonData["document"], jsonData);
                return Content(JsonConvert.SerializeObject(jsonResult));
            }
            else
            {
                return Content("Error! Document data not available.");
            }
        }
