PDF Conversion Not Working

[Jack Simone]

On my development machine I have an MVC 4.6.1 site functioning well, successfully producing a PDF from a web page using the Syncfusion libs and the Webkit rendering libs, which I placed in ~/bin/QtBinaries. Works great! However, the same web application code on the production server fails when doing the conversion. I'm having trouble tracking down the cause of this Exception. I've tried some debugging, and can say that the target URL to get the HTML content is never hit with an HttpRequest. I use ASPHostPortal as my hosting. Here's the Syncfusion.PdfException stack trace:

Syncfusion.Pdf.PdfException: Failed to convert the webpage at Syncfusion.Pdf.HtmlToPdf.HtmlToPdfResult.RenderWebKit(PdfPageBase page, PdfLayoutFormat format) at Syncfusion.Pdf.HtmlToPdf.HtmlToPdfResult.Render(PdfPageBase page, PdfLayoutFormat format) at Syncfusion.HtmlConverter.HtmlToPdfConverter.Convert(String url) at RuralData.Controllers.FormsController.d__11.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at System.Web.Mvc.Async.TaskAsyncActionDescriptor.EndExecute(IAsyncResult asyncResult) at System.Web.Mvc.Async.AsyncControllerActionInvoker.<>c__DisplayClass37.b__36(IAsyncResult asyncResult) at System.Web.Mvc.Async.AsyncResultWrapper.WrappedAsyncResult`1.CallEndDelegate(IAsyncResult asyncResult) at System.Web.Mvc.Async.AsyncResultWrapper.WrappedAsyncResultBase`1.End() at System.Web.Mvc.Async.AsyncControllerActionInvoker.EndInvokeActionMethod(IAsyncResult asyncResult) at System.Web.Mvc.Async.AsyncControllerActionInvoker.AsyncInvocationWithFilters.b__3d() at System.Web.Mvc.Async.AsyncControllerActionInvoker.AsyncInvocationWithFilters.<>c__DisplayClass46.b__3f() at System.Web.Mvc.Async.AsyncControllerActionInvoker.<>c__DisplayClass33.b__32(IAsyncResult asyncResult) at System.Web.Mvc.Async.AsyncResultWrapper.WrappedAsyncResult`1.CallEndDelegate(IAsyncResult asyncResult) at System.Web.Mvc.Async.AsyncResultWrapper.WrappedAsyncResultBase`1.End() at System.Web.Mvc.Async.AsyncControllerActionInvoker.EndInvokeActionMethodWithFilters(IAsyncResult asyncResult) at System.Web.Mvc.Async.AsyncControllerActionInvoker.<>c__DisplayClass21.<>c__DisplayClass2b.b__1c() at System.Web.Mvc.Async.AsyncControllerActionInvoker.<>c__DisplayClass21.b__1e(IAsyncResult asyncResult)

Any insights maybe?

Hi Jack, 

We faced this issue with our other customers also and all the possible cause and solution are documented in the provided KB link. So please double check this in your server machine. However, if you need our assistance please create a new Ditect-trac incident stating with this forum ID. So that we can have a web meeting and look into your machine directly and resolve your issue.
