**Edit:
BUG FOUND: I found the "invalid stylesheet". It is S28 in this case, there is no 'name' in front of the semicolon. This creates an extra space before the semi-colon. I found other instances of "sl0 ;" that worked fine. It's that extra space ('sl0 . ;') that was causing the issue.
So a bit of a background, we are taking .rtf files created in a medical EMR (Epic) and converting them to .tiffs for a vendor. Most all of the files are fine, but there are a few that are getting formatted weirdly, but I can't figure out why. What happens is the error pops up which stops the conversion script (Which basically just opens Word and prints it via file to tif). The error I'm getting is:
"This is not a valid style name."
Is there a way to trace this to figure out what exactly is causing the problem? I have searched and the very very few results that came up point to the filename (Which is fine. Even renaming does not help). Here is a copy of the stylesheet information (broken down), which may or may not help:
