Issue with current documentation:

I was running the code in the "How to use the output-fixing parser" page. After running the last line of code new_parser.parse(misformatted) instead of fixing it and returning the correct output, it gives an error:

ValidationError: 1 validation error for Generation
text
  str type expected (type=type_error.str)

Idea or request for content:
