Flask has a useful debug mode that allows code to be interactively debugged from a web GUI in the event of a program tracebook. To use this feature, set this value to True, and run the app from the command line from inside the DNS Integrity Gateway container (cd /portal; ./app.py).
Attention: You must set this value to False when you deploy into a
production environment.
# Run in debug mode, must not do this in a production environment. debug=True
