Object reference not set to an instance of an object when using Table Extraction from PDF

Hello! First, I want to thank the developers for their hard work with the Aspose’s App. It helped me tremendously!

I have a problem when I want to extract a table from the pdf, it shows like this:
“Object reference not set to an instance of an object”

This is the pdf that has the problem

Data dan Informasi Kemiskinan Kabupaten_Kota Tahun 2017.pdf (7.1 MB)

I wonder what’s wrong, can you help?

Thanks again!
