The issue you're experiencing with the file widget truncating PDF content at 7 or 8 pages might be related to the PDF parsing method used in Langflow. The library pypdf is used for PDF parsing, specifically the PdfReader class, which extracts text from PDF files ^[1]. There might be a limitation or bug in how the parse_pdf_to_text function processes the pages, or there could be a configuration setting affecting this behavior.

To address this, you might want to check if there are any updates or patches available for the pypdf library or Langflow itself that address this issue. Additionally, reviewing the implementation of the parse_pdf_to_text function could provide insights into any potential limitations or areas for improvement.
