Comment (by MadtownLems):

 I had similar errors logged, and I traced it down to when sites were using
 Images that were generated by uploaded PDFs. The metadata for those pdf
 thumbnails does not seem to contain the base 'file' attribute.

 What I can't actually figure out is how our users even got the URLs to use
 those images on the front-end! 😅 .
