Bug

The /pdf/{id} route in hero_books_ui renders the raw HTML source of the markdown page instead of converting it to an actual PDF document.

Steps to Reproduce

  1. Run make demo in hero_books
  2. Open a book page in the UI
  3. Click the PDF export/download link
  4. Browser shows raw HTML tags (<meta>, <div>, etc.) instead of a formatted PDF

Expected

The PDF route should render the markdown content as a properly formatted PDF document.

Screenshot

URL: localhost:8080/pdf/1174b68654ca2719 shows raw HTML source code in the PDF viewer.

Repo

  • lhumina_code/hero_books — crates/hero_books_ui/ (the Bootstrap UI)
