Access Github Secrets in Python workflow - python-3.x

Question

I have an issue with access Github Secrets in CI workflow
the tests part of main.ymlfile -
# Run our unit tests
- name: Run unit tests
env:
CI: true
MONGO_USER: ${{ secrets.MONGO_USER }}
MONGO_PWD: ${{ secrets.MONGO_PWD }}
ADMIN: ${{ secrets.ADMIN }}
run: |
pipenv run python app.py
I have a database.py file in which I am accessing these environment variables
import os
import urllib
from typing import Dict, List, Union
import pymongo
from dotenv import load_dotenv
load_dotenv()
print("Mongodb user: ", os.environ.get("MONGO_USER"))
class Database:
try:
client = pymongo.MongoClient(
"mongodb+srv://" +
urllib.parse.quote_plus(os.environ.get("MONGO_USER")) +
":" +
urllib.parse.quote_plus(os.environ.get("MONGO_PWD")) +
"#main.rajun.mongodb.net/myFirstDatabase?retryWrites=true&w=majority"
)
DATABASE = client.Main
except TypeError as NoCredentialsError:
print("MongoDB credentials not available")
raise Exception(
"MongoDB credentials not available"
) from NoCredentialsError
...
...
this is the issue I get in the build-
Traceback (most recent call last):
Mongodb user: None
MongoDB credentials not available
Followed by urllib raising bytes expected error
I have followed the documentation here but I still cannot find out my mistake
