Is it the project property 'Required Client Roles' that you are talking about ? If it's the case it's empty in my project. You can access my project without be logged in, but some functionalities like buttons require you to be logged in to use them.
Also I noticed something, I don't know if it's useful or not, but I tried this by logging in on the main view every times, but in the logs of the gateway in the logs properties of the error, there is a different view for all messages:
After the login screen it's supposed to take me back to the main view so I don't know why the view in the log properties is changing.
