Hi Philo,

Thanks for your inquiry. Could you please attach your input Word document and code here for testing? I will investigate the issue on my side and provide you more information.

Best regards,

I can’t as document is classified. Can ensure you that it is quite simple document.

Can’t you tell where is the issue by stack trace?

Hi Philo,

Thanks for your inquiry. Unfortunately, it is difficult to say what the problem is without the document and code. I need your document and piece of code from your application to reproduce the same problem on my side.
Please note that it is safe to attach files in the forum. If you attach your document here, only you and Aspose staff members can download it. You can also send the file to my e-mail as described here:

You can also remove any sensitive information from your document by replacing it with dummy data instead.
Best regards,
