Configuration Error when trying to connect mongodb database in python

Question

I keep getting pymongo.errors.ConfigurationError: query() got an unexpected keyword argument 'lifetime' even though I have all the latest versions of pymongo and dnspython installed. This is my code...

import pymongo

client = pymongo.MongoClient("mongodb+srv://Nethrenial:[email protected]/TooDooo?retryWrites=true&w=majority")
users = client.users.find()
user_list = []
for user in users:
    user_list.append(user)
print(user_list)

And this is the complete exception,

Traceback (most recent call last):
  File "C:\Users\lenovo\AppData\Local\Programs\Python\Python39\lib\site-packages\pymongo\srv_resolver.py", line 72, in _resolve_uri
    results = resolver.query('_mongodb._tcp.' + self.__fqdn, 'SRV',
TypeError: query() got an unexpected keyword argument 'lifetime'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "C:\Users\lenovo\Desktop\TooDooo\database_functions.py", line 4, in <module>
    client = pymongo.MongoClient("mongodb+srv://Nethrenial:[email protected]/TooDooo?retryWrites=true&w=majority")

Answer 1

If you use Python 3, you must use dnspython3 instead of dnspython. This lib actually uses dnspython under the hood, but installs an incorrect version, 1.15.0, the same as for main library. You must change it manually to 2.1.0. On PC (Windows) it also installs starlette lib. Never change it's version to upgrade, it stops working.

Incompatibility issues and poor ecosystem support seems to be a common problem in the Python world.

Answer 2

In Most cases, this occurs because of outdated dnspython lib. I solved my issue just by re-installing / updating dnspython

pip3 install dnspython
