I’m currently evaluating your product and use it to index E-Mails. I’ve found some E-Mails which are throwing NullReferenceException within the method
Converter.ConvertMHTML(htmlStream, pdfSaveOptions, tempFileNamePdf);
which converts an MHTML to PDF.
The MHTML is loaded from an .eml-File with your componenten Aspose.Email and converted to MHTML.
I will attach a sample Visual Studio solution which shows the NullReferenceException quickly.
This happens with Aspose.HTML (.NET) in Version 22.9.0.
