Ok I see the problem, you are using Python 3 to run your Heroku application.

The line 2018-09-13T04:54:13.237931+00:00 app[web.1]: File "/app/.heroku/python/lib/python3.6/site-packages/gevent/hub.py", line 289 specifically says you are using the Python 3.6 runtime, and the gevent library you are using is meant for Python 2. (The Exception is using Python 2 syntax)

Check the runtime.txt in your projects root folder and ensure it says "python-2.7.15", Heroku has docs on specifying the python runtime for your application https://devcenter.heroku.com/articles/python-runtimes.
