Load PDF failed

[Andre Karner]

Dear community,

since 2 hours im trying to load an pdf through stream or local file into my pdf viewer.

everytime im getting an exception: "The given key was not present in the dictionary".

This exception occurs when im executing following method "var output = helper.ProcessPdf(jsonResult);"

My View:

@using Syncfusion.JavaScript.PdfViewerEnums
 
@{
    ViewBag.Title = "Rechnungsansicht";
}
 
<h2>Rechnungsansicht</h2>
 
@Html.EJ().PdfViewer("invoicePdfViewer").ServiceUrl("/Invoice").PdfService(PdfService.Local);

My Controller action:

public object PostViewerAction(Dictionary<string, string> jsonResult)
       {
           if (Request?.UrlReferrer != null)
           {
               var invoiceIdStr = HttpUtility.ParseQueryString(Request.UrlReferrer?.Query)["invoiceId"];
 
               if (string.IsNullOrEmpty(invoiceIdStr))
                   throw new Exception("Rechnung nicht gefunden!");
 
               var invoiceId = Convert.ToInt32(invoiceIdStr);
 
               var helper = new PdfViewerHelper();
 
               //var t = new Thread(GetInvoicePdf);
               //t.SetApartmentState(ApartmentState.STA);
 
               //t.Start(invoiceId);
               //t.Join();
 
               helper.Load(@"C:\tmp\R000001.pdf");
 
               var output = helper.ProcessPdf(jsonResult);
               var response = JsonConvert.SerializeObject(output);
               return response;
           }
 
           return null;
       }

Please help me!

Thanks!

Andre
