PDFs not working unless I add poppler-utils to Aptfile

[oskargargas]

Hi!

I have problems rendering PDFs in current setup on Heroku-20. It was fixed after I added poppler-utils to the Aptfile though not sure if this is recommended solution.

Regards,
Oskar

Interesting, thanks for sharing this. The long term plan is to switch PDF providers to PDFium, so hopefully this issue will resolve itself. In the meantime, the issue is here to help anyone else if they experience the same issue. Thanks again!
