Two file python project not starting on heroku.com?

Question

Python

The whole point in the question is there are 2 python files that are connected to each other on one bot for the telegram on the second the router control logic is written, on the PC everything works as soon as I upload to heroku nothing works the bot does not respond to requests
Heroku errors:

-----> Python app detected

requests and TPlink are written in the requirements file (this is a file with the router logic that is used through import)
worker is written in the Procfile file: python RouterBOT.py (this is a telegram bot)
