Python Telegram bot on Heroku can't access Google Spreadsheet - heroku

Question

I am deplying a python program on Heroku. Everything works fine locally, but it doesn't seem to run on Heroku
The bot.py file contains two variables which are saved as config in Heroku: TOKEN and SPREADSHEET, these are the Token of the telegram bot and the ID of the google Spreadsheet I am trying to access.
When the code is running on Heroku, I get this:
The code seems to be running on the Heroku server, but when I try to send the command on the Telegram bot, it doesn't work

Answer 1

I had the same issue with my telegram bot.
I added the actual bot token string to the TOKEN variable and uploaded it to Heroku.
Then I used os.environ.get('TOKEN') command for the version that I pushed on GitHub.
I am still just a beginner in python, I don't know if this posses security issues but it removed the error code and allowed my bot to work
