reader.get_fileds() do not work on a written PDF And the fields written/updated do not display, only when u click.

Hi,

Couple of problems:

1. reader.get_fileds() do not work the second time if you try to read the file that you just written to.
2. The written value does not reflect in the written file but only shows up when you click on the field (see video)

• Used the forms code from here https://pypdf2.readthedocs.io/en/latest/user/forms.html

• PDF sample https://royalegroupnyc.com/wp-content/uploads/seating_areas/sample_pdf.pd

  from PyPDF2 import PdfReader, PdfWriter
  
  def reRead(filename):
      reader = PdfReader(filename)
      writer = PdfWriter()
      page = reader.pages[0]
      fields = reader.get_fields(). # <- this is empty when you read the output pdf from previous time.
      writer.add_page(page)
      
      writer.update_page_form_field_values(
              writer.pages[0], {"Name": "hello1"}
          )
      with open("filled-out.pdf", "wb") as output_stream:
          writer.write(output_stream)
  
  # first time works
  reRead("templates/sample_pdf.pdf")
  # second time doesnt work
  reRead("filled-out.pdf")
