I have built an API server with python's Flask package. I'm trying to deploy the server on Heroku using the terminal but doesn't seem to work. I have already tried using the Heroku Build Pack to install packages listed in the Aptfile with contents:
libicu-dev
pkg-config
python3-icu
python3-setuptools
I also added the and Python Build Pack in the Heroku Web Dashboard. During the installation of Apt Packages here's the output I get with the Heroku Build Pack:

Then after the Heroku build pack is completed, it moves to the Heroku/python build pack which yields the following error:

Perhaps I might be missing one simple thing. I would appreciate any kind assistance.
Thank you.
