I am using the pdf extraction function provided here on my own PDF files: https://developer.adobe.com/document-services/docs/overview/pdf-extract-api/howtos/extract-api/

 

Whenever I try and extract tables, the program throws this error:

INFO:adobe.pdfservices.operation.pdfops.extract_pdf_operation:All validations successfully done. Beginning ExtractPDF operation execution
ERROR:adobe.pdfservices.operation.internal.api.cpf_api:Failed in parsing Extract Result

Extracting just text appears to work fine, but as soon as I try and throw tables into the mix it breaks it. This is an issue as I am pretty much only using this API for its table extraction. Does anyone know a fix for this?

I found a solution! Turns out you need to specify the TableStructureType by adding .with_table_structure_format(TableStructureType.###) to your ExtractPDFOptions
