Error received when exporting

I am attempting to export a Powerpoint PPTX file that has all of the slides hidden.
I get a "General input/output error" (screenshot attached).

I originally experienced this attempting to convert the PPTX to PDF using unoconv.
The error I received when doing that was:

Input file: /tmp/presentation.pptx
unoconv: UnoException during export phase:
Unable to store document to file:///tmp/presentation.pdf (ErrCode 3088)

If I add at least one non-hidden slide, or use the "-e ExportHiddenSlides=true" flag to unoconv, the export succeeds.

My use case for this is that I am converting uploaded PPTX files to PDF automatically, so I have no control over the content of the file and cannot simply unhide the slides.
