Research direction

Start with the parser stack in node_modules/pdf2json/lib/pdf.js and the reported input PDF path. Reproduce the failure with the confidential PDF, if it can be provided, and trace the illegal-character error and command warnings during page parsing. Done means the PDF parses without the reported rejection and command-argument warnings.

Description

Hi,

I was using this lib for last few months, but 2 days back i am unable to parse the pdfs. after enabling the logs i see following errors.

Since test file is confidential I cannot publish it here. I can provide the same via email on request.

Can you please help.?
