Optimize Node errors

[JJakubowski]

It appears the error message is pointing you to a log file in:

\Xerox\FreeFlow\Core\00000000-0000-0000-0000-000000000000\Platform\Spool\d4cc7eb7-8698-4c57-a3dd-4d13d67766b2\280730_Summit_Wilson_County_Mailer_2-13-2020_1UP.pdf_FixupError.log

I have an Optimize Node that is set to convert files to PDF/X-4, but it fails on some files; anyone know why? I don't get any information other than this error message:
