Badly formatted number

[howardbaik]

I have downloaded these Google Slides to pdf and am converting them to png: https://docs.google.com/presentation/d/1IJ_uFxJud7OdIAr6p8ZOzvYs-SGDqa7g4cUHtUld03I/edit?usp=sharing

Whenever I run pdf_convert(), I'm getting this error message: PDF error (4890998): Badly formatted number. The number in the parenthesis varies depending on the slide number. The error message doesn't stop the function from running through all the slides though. Also, the png files of the slides that get this error message do not look distorted or broken. They look fine to me.

Do you know what may be causing this error message?

The warning message also exists using poppler::pdfimages natively, and seems purely informative :

So maybe you should open the issue in the poppler repository ?
