OCR workflow not working for specific documents

[snam24]

It's stuck at the embedding stage. I've tried a solution to #7 but it did not help.
The output file such as original_filename (ocr).pdf is corrupted and can't be opened. Please see the debug below. When I open up the progress bar with typing ocr on Alfred, the debug goes on and on.

Hey @snam24
If clearing the cache files as described in #7 doesn't resolve the issue (/Users/myname/Library/Caches/com.runningwithcrayons.Alfred/Workflow Data/com.zeitlings.ocr), the problem might be related to the specific document you're trying to perform OCR on.

• Is this happening with all PDFs or just specific documents?
• If possible, could you share the PDF that's causing the issue? This will allow me to investigate further and potentially identify the root cause.

Hi @zeitlings,

Thanks for getting back to me. I tried another document and it worked. I guess it's related to the specific files as you said. I'm afraid I cannot upload/share the pdfs on the public space, but you can download them below if you have access. Thanks!

Hey @snam24
Thanks for sharing that info and providing the sources! I'll definitely take a closer look when I have some time.
