Bug: Assertion error resulting in the abortion of extraction

[chrisgrieser]

This looks look a similar case like issue #48.

Once again, I have a PDF file which is a book scan, and get a warning about popup annotations not being supported. And instead of continuing, an Assertion Error results in the abortion of the annotation extraction.

This time, I couldn't break it down to a particular page – the issue seems to occur regardless of the page tried. I have therefore attached a sample of 10 pages, and the log I get.

Yes, that looks exactly like #48. Which version of pdfannots are you using? I notice you've installed it from a package (e.g. from PyPI), but the warning about Popup annotations is removed in the latest version, so I wonder whether you are missing the fix I made for that issue.

Indeed, your sample works fine for me. Please reopen if you can repro on the latest version.

ah yes indeed, I was still on 0.2. After updating to 0.3, everything works.

thanks and sorry for the waste of time!
