I'm running the demo code of Python Eve and I'm having troubles with the Auth part. The code I'm running is identical as the repo, except for MongoDB URI in settings.py.
# We want to seamlessy run our API both locally and on Heroku. If running on
# Heroku, sensible DB connection settings are stored in environment variables.
MONGO_URI = 'mongodb://****:****@localhost:27017/admin'
MONGO_DBNAME = 'apitest'
Everything works fine if I put correct credentials in Basic Auth (which are user=admin passwd=secret) but if I don't put Authorization header or correct credentials I don't get a 401, as I would expect, but the application crashes returning 500. This is the traceback.

I was able to reproduce the issue with just flask. Looks like it has to do with latest werkzeug release. Flask doesn't specify which werkzeug to use and just says anything above 0.14 so you automatically get the latest version (0.15.1 as of today) and on. Version 0.15.0 changes implementation of http exceptions a little, specifically this bit right here introduced the Unauthorized http exception constructor, so it now does not accept that response argument. Before it simply extended HTTPException.
So I suggest to simply pin a spicific version of werkzeug in your project requirements. Anything below version 0.15, say 0.14.1 should work for you.
What else you can do:
