We are facing difficulties in converting word documents having index pages. The converted PDF shows an error for indexes – “Error! Hyperlink reference not valid!”.
Have you tried the latest (21.9) version of Aspose.Words for .NET on your end? In case the problem still remains, then please ZIP and upload your input Word document and Aspose.Words generated PDF file showing the undesired behavior here for testing. We will then investigate the issue on our end and provide you more information.
