I've deployed this project throw zappa on Ubuntu 18.04 Lts So, I visit https://myurl.execute-api.us-east-2.amazonaws.com/dev and there is this error

"{'message': 'An uncaught exception happened while servicing this request. You can investigate this with the zappa tail command.', 'traceback': ['Traceback (most recent call last):\n', ' File \"/var/task/handler.py\", line 452, in handler\n response = Response.from_app(self.wsgi_app, environ)\n', ' File \"/var/task/werkzeug/wrappers.py\", line 903, in from_app\n return cls(*_run_wsgi_app(app, environ, buffered))\n', ' File \"/var/task/werkzeug/test.py\", line 884, in run_wsgi_app\n app_rv = app(environ, start_response)\n', \"TypeError: 'NoneType' object is not callable\n\"]}"
