"App not compatible with buildpack: https://buildpack-registry.s3.amazonaws.com/buildpacks/heroku/python.tgz" Selenium Python gspread script Deploy

Question

I am trying to deploy a Selenium Script on Heroku, I have added all required buildpacks, and also added environment variables, but when I deploy, it gives the error...

I have tried to deploy using CLI, as well as through Github, but still, same issue.
I have also tried this as Procfile

worker: python main.py

Procfile :

web: python main.py
