pymongo: Resolver configuration could not be read or specified no nameservers

It's my first time using MongoDB but I can't seem to fix this one issue, my friend who uses MongoDB doesn't know how to use python so he can't really help me.
Here's my code:
import pymongo
# Replace the uri string with your MongoDB deployment's connection string.
conn_str = "mongodb+srv://sqdnoises:{mypass}#sqd.d4kjb.mongodb.net/myFirstDatabase?retryWrites=true&w=majority"
# set a 5-second connection timeout
client = pymongo.MongoClient(conn_str, serverSelectionTimeoutMS=5000)
try:
print(client.server_info())
print('\n\n\n aka connected')
except Exception:
print("Unable to connect to the server.")
Where {mypass} is my MongoDB password.
I keep getting this error:

How do I fix this?
I am following https://docs.mongodb.com/drivers/pymongo/

indeed, the problem is that dnspython tries to open /etc/resolv.conf
import dns.resolver
dns.resolver.default_resolver=dns.resolver.Resolver(configure=False)
dns.resolver.default_resolver.nameservers=['8.8.8.8']
Just adde this code to the top of your main code, and that should be sufficient to get you past this hurdle..

Twitter app requires python 3.6.13 to run but Dockerfiles' similar alpine version is not working. Running into mismatch of python package

The Twitter bot app requires python 3.6.13 to run. While dockerizing it, Dockerfile has alpines' python versions which is not meeting my apps requirement.
How can I install python 3.6.13 in a Dockerfile?
For example, in my case, I tried initiating a docker file like this
FROM python:3.6-alpine
COPY bots/config.py /bots/
COPY bots/stream.py /bots/
COPY requirements.txt /tmp
RUN pip3 install -r /tmp/requirements.txt
WORKDIR /bots
CMD ["python3", "stream.py"]
After creating the docker container, the app crashes due to pythons mismatch of versions.
Later I tried this with the version I want:
FROM python:3.6.13
COPY bots/config.py /bots/
COPY bots/stream.py /bots/
COPY requirements.txt /tmp
RUN pip3 install -r /tmp/requirements.txt
WORKDIR /bots
CMD ["python3", "stream.py"]
the python package is very large unlike alpine provides.
But When I tried this:
FROM python:3.6.13-alpine
COPY bots/config.py /bots/
COPY bots/stream.py /bots/
COPY requirements.txt /tmp
RUN pip3 install -r /tmp/requirements.txt
WORKDIR /bots
CMD ["python3", "stream.py"]
It looks like it worked as the program started execution but I got another new error which is this:

Is there anything that I can do to avoid this exception error?
Later, I tried to add the python version that I want in the requirements.txt file but it didn't work.
I found up a source but couldn't understand but I feel the answer is here, source.
Is there any way I can instantiate the python 3.6.13 version in the Dockerfile so that it uniformly supplies this version to the whole image and the app?

PermissionDenied: 403 error when I'm using Google Cloud Billing Budget API

I'm using Google cloud functions and the Cloud Billing Budget API to get a list with all of my budgets, but I'm having the following error:

What I've done is give the appropriate permissions (billing.budget.list ... billing.budget.get ... etc ) at the organization level to the service account of the function, but it does not work.
My code is this:
#main.py
import os
import get_budgets
from google.cloud.billing import budgets
def getting_data(data, context):
BILLING_ACCOUNT = 'billingAccounts/XXXXXX-XXXXXX-XXXXXX'
client = budgets.BudgetServiceClient()
all_budgets = client.list_budgets(request = {'parent': BILLING_ACCOUNT})
budget_actions.budget_list(all_budgets)
#get_budgets.py
from google.cloud.billing import budgets
from googleapiclient import discovery
#BUDGET LIST
def budget_list(all_budgets):
print('Budget summary')
for budget in all_budgets:
print(f'Name: {budget.display_name}')
b_amount = budget.amount
if 'specified_amount' in b_amount:
print(f'Specified Amount: {b_amount.specified_amount.units} {b_amount.specified_amount.currency_code}')
if 'last_period_amount' in b_amount:
print('Dynamic spend (based on last period)')
print('')
Is there something that I've forgotten?

The solution to my problem was easier than I expected.
What I've done is add the service account as a member of the billing account.
Here is a quick video from Google of how to do it
https://www.youtube.com/watch?v=Vti0OGQfLHQ
And in the comments of my question, you can find additional details.

Most likely you have created your app with authentication set to only allow users from your Google Apps domain, but you're attempting to access appstats via the appspot.com subdomain. Try again using the URL for your app on your custom domain.
