KeyError: '/Annots' in update_page_form_field_values

[javialon26]

I'm filling a PDF file with the update_page_form_field_values method but if the PDF file contains at least one page without a field a KeyError was thrown.

Environment

Which environment were you using when you encountered the problem?

$ python -m platform
Linux-5.10.104-linuxkit-x86_64-with-glibc2.31

$ python -c "import PyPDF2;print(PyPDF2.__version__)"
2.10.6

Code + PDF

This is a minimal, complete example that shows the issue:

for idx, page in enumerate(reader.pages):
            writer.add_page(page)
            writer.update_page_form_field_values(
                writer.get_page(idx), self.data, FieldFlag.READ_ONLY
            )

Traceback
