Ошибка Объект 'NoneType' не имеет атрибута 'is_absolute' при использовании mongodb

Тип исключения: AttributeError

Значение исключения:
У объекта 'NoneType' нет атрибута 'is_absolute' Расположение исключения: C:\Users\A\IPFinder\venv\lib\site-packages\dns\resolver.py, line 1006, in _get_qnames_to_try

Исполняемый файл Python: C:\Users\A\IPFinder\venv\Scripts\python.exe

при загрузке файла кнопка submit должна сохранить файл, но при запуске action_page.py код выдает ошибку 'NoneType' object has no attribute 'is_absolute'

.

action_page.py

import cgi import os import cgitb; cgitb.enable()

form = cgi.FieldStorage()
fileitem = form['filename']

if fileitem.filename:
    fn = os.path.basename(fileitem.filename)
    open(fn, 'wb').write(fileitem.file.read())

это мой index.html
