Thumbnails for OCR'ed pdfs not generating

Any recommendations on how to troubleshoot thumbnail generation for OCR'ed pdfs? When we upload OCR'ed pdfs, the thumbnail image is broken, and the thumbnail image file doesn't exist when checking the media directory. However, if we upload the same pdf but not OCR'ed, the thumbnail generates fine. We've tried manually running the ghostscript command line to generate an image of OCR'ed pdfs, and that works.

  • Do you have Ghostscript installed on this machine? If so, what version is installed?

  • We have version 8.7 installed
