heroku deployment not working

[scheung38]

Locally, submitting email and clicking on Chat takes user to Chat page, but testing a deployment to heroku

https://flaskchatfin.herokuapp.com/

but after submitting email, it remains in the same landing page?

While in local Mac, foreman start also fails:

But launching from Pycharm is able to start the app, by right clicking run_server.py.
