Hi @jpmv27, does opening images and videos in the viewer still work? If so, this might be related to issue #381, could you test if its solution (PR #384) resolves this issue for you? To do this, could you replace
apps/files_pdfviewer/js/files_pdfviewer-main.js on your instance with this file from that PR. Clear your browser's cache and try to open pdfs again.

Thank you @beardhatcode, that resolved the issue.
I did see that issue before I opened this one, but overlooked the fact that there are spaces in the paths of the PDFs I tried to open.

Happy to hear that your issue has been resolved.
