We've been testing Adobe PDF Extract API to extract table information from PDFs using the code samples provided by Adobe. It has been working good for almost 80% of the files we tested, but for the rest 20%, we keep getting empty results (already checked that the PDF contains information to be extracted). There's no error response, we even get a json file, but without extracted info or tables.
We tested the following appoaches:
1. Extracting tables (it's already a searchable PDF)
2. Running OCR and then extracting table (just to confirm)
We got empty results for both cases on that PDF files. Has anyone experienced this? Is there a workaround?
