Errors with deploying website using Heroku/Flask Server

Question

I am trying to deploy a website using Flask/SQLAlchemy to host my data base using waitress. I did try to follow this link but I don't think my file structure is the same Heroku + node.js error (Web process failed to bind to $PORT within 60 seconds of launch)

Here is my file structure

Server
->BarBeerDrinker
 ->__pycache__
 ->static
 ->__init__.py
 ->configt.py
 ->database.py
->app.py
->Procfile
->requirements.txt

When after trying to access my website I type this into my console heroku log --tail and this is what I get.

I am very new to trying to deploy a website and I honestly just followed the basic instruction that my professor gave to us here https://drive.google.com/file/d/1dltcKrigTvtJk3hHvl7I_y0KnlGuy3V9/view?usp=sharing

Answer 1

The PermissionError indicates that you likely need to give executable permissions to a file. Try giving permissions to runner.py and/or server.py.

chmod 777 /path/to/runner.py
chmod 777 /path/to/server.py

777 will give broad permissions for read/write/execute to owner/group/other. You may want something more specific like chmod 755 path/to/file.py. See the man page for chmod here.
