I was dealing with a document triggered this error in papermage/rasterizers/rasterizer.py:
raise ValueError(f"Failed to attach. {len(images)} images != {len(pages)} pages in doc.")
I did a deep debug found that the reason is my pdf has a blank page, and this code, in papermage/parsers/pdfplumber_parser.py, to determine the number of pages is by traversing the existence of all the objects, which will skip the blank page, resulting in the number of page objects in page_annos list to be less than the actual number of pages.

page_annos.append(page)Some further modifications may be needed here to deal with this rare case. Thank you.
