Converting EBook crashes on Mac and Linux

We use a common component for converting various documents to PDF.
The component runs on Windows, Mac and Linux.
Converting the attached EBook works fine on Windows but fails on Mac and Linux.

The code for converting:
Aspose.Pdf.EpubLoadOptions option = new Aspose.Pdf.EpubLoadOptions();
using (Aspose.Pdf.Document pdfDocument = new Aspose.Pdf.Document(importFile, option))
pdfDocument.Save(pdfFile);

Stack from Mac:
System.NullReferenceException: Object reference not set to an instance of an object. at #=zBLNT1q$kVkwj5brabTwrwLvaPWAKY1jJu$tllZ8=.#=zQbDdeBu23vvT
