Hi, i'm using PdfViewer and an unhandled ArgumentNullException exception appears periodically on some files.

I saw that there was a already similar error, written in this post   https://www.telerik.com/forums/argumentnullexception-after-scrolling-pdf-document   and that error has been fixed. But i'm using the new version of telerik - 2019.2.618. This error is reproduced in the examples from "xaml-sdk", on FirstLook project.

The error can be reproduced by downloading the file from this link   https://beginners.re/RE4B-EN.pdf. On the 39 page below there is a link that does not have a destination   -   "29 STMFD 30". The 30 link does not link anywhere, and when PdfViewer try to create destination, it falls with exception.
I check the Destination property in GoToActionOld object before create object Destination. It helped for me.

private static GoToAction CreateGoToAction(GoToActionOld source, PdfFormatProvider provider)
{
    Guard.ThrowExceptionIfNull(source, "source");
    if (source.Destination == null)
    {
        return null;
    }
    return new GoToAction
    {
        Destination = CreateDestination(source.Destination, provider)
    };
}

Here is a StackTrace:
System.ArgumentNullException
  HResult=0x80004003

Please check and correct the error, because I have to keep a separate fixed library.

Any idea if this is being worked on. We too are bumping into the exception. The PDF file we have the exception with is generated by our in-house tech writer. What can she do to verify what may be wrong with the document? Thanks.
