System.InvalidCastException is thrown while saving DOCX to PDF using .NET


I get the following exception when saving the attached sample Word document Issue.zip (17.0 KB) as PDF with revision balloons using Aspose.Words for .NET 20.2.0 :

System.InvalidCastException: ‘Unable to cast object of type ‘Aspose.Words.HeaderFooter’ to type ‘Aspose.Words.Body’.’

using the following C# code to reproduce :

var doc = new Document(path);

doc.LayoutOptions.RevisionOptions.ShowInBalloons = Aspose.Words.Layout.ShowInBalloons.FormatAndDelete;

doc.Save(doc.OriginalFileName + ".pdf", SaveFormat.Pdf);
