No module named 'requests' - Django deployment onto Heroku - django

Question

Deployed some new code into an app on Heroku and now showing the following message: No module named 'requests' . The app was working fine before, so this has to be something I changed.
Before I show the code there is 2 things that I noticed: my Procfile & requirements files are not visible from Visual Studio (can be seen from Sublime Text Editor). Recently started using VS and only noticed it now. Not sure if this is of importance here.
I am not sure where the error is coming from so I left below traceback, Procfile and requirements.txt files.
Let me know if I need to add something else.

Answer 1

You have to add requests in Requirements.txt like this :
requests==2.28.1

Answer 2

Install request by running the below command
pip install requests
Then update your Requirements.txt just run
pip freeze > Requirements.txt
This will add all libraries that you have used in the project including the newly installed.
