I think I know the source of the problem. I first had to add a logging section for "openstack_dashboard" in local_settings.py despite the fact that there was already a section for "horizon". Then I was able to see the exception that was happening:

    ServiceCatalogException: Invalid service catalog service: volume

I don't have Cinder installed, but it looks like Horizon is expecting it to be there. I don't have a volume endpoint, as far as I can tell. "nova endpoints" only lists glance nova, ec2 and keystone.

Is there a way to disable this behaviour in Horizon? Or is there a setting I'm missing?

Thanks,
Daniel
