Does anyone know how to deal with this?

Can you open it in an incognito browser and check the behavior.
This exception looks like a request without authentication credentials which throws this Exception as security is now enabled.

How are you executing this request? If it came from a Browser, then you'd be prompted for authentication (Basic Authentication) . If you're using i.e. curl , you need to pass the credentials with your request with -u username:password
