TypeError: unsupported operand type(s) for +: 'int' and 'NoneType'

Thanks, we will try to fix it.

I've fixed this issue in my fork. Calculate_page_offset can return None, which then causes a TypeError when add_page_offset_to_toc_json tries to do data[i]['page'] + offset.

The fix defaults offset to 0 when calculate_page_offset returns None

PR with the fix: #154
