Why is the bot on Heroku Server not responding? - heroku

Question

I programmed a simple bot that is connected to Google Sheets API. It asks a few questions to the user and stores it in the Sheet I have. When I use bot.polling it works fine, but I was trying the webhook so I could use Heroku to have my bot running 24/7.
I introduced the code:
#server.route('/' + token, methods=['POST'])
def getMessage():
bot.process_new_updates([telebot.types.Update.de_json(request.stream.read().decode("utf-8"))])
return "!", 200
#server.route("/")
def webhook():
bot.remove_webhook()
bot.set_webhook(url = '<Heroku App Link>' + token)
return "!", 200
if __name__ == "__main__":
server.run(host="0.0.0.0", port = int(os.environ.get('PORT', 5000)))
I have the requirements.txt file and the Procfile that currently is like this:
web: python3 bot.py
I tried a bunch of things in the Procfile but this is the only one that didn't gave an error.
When I saw the log this is what I got:

Can anyone help me understand why the bot doesn't answer any commands?
