openstack image create throws BadRequestException

Question

I've installed ussuri version of openstack and everything seems to be fine, but there is a wierd problem in glance. When I use glance image-create command, everything is fine and it works correctly, but, when I use openstack image create command, as I mentioned below:

openstack image create --public --protected --disk-format raw --file ubuntu.raw ubuntu

it throws this execption:

BadRequestException: 400: Client Error for url: http://controller:9292/v2/images, Provided object does not match schema 'image': 'True' is not of type 'boolean': Failed validating 'type' in schema['properties']['protected']:: {'description': 'If true, image will not be deletable.',: 400 Bad Request: 'True': 'type': 'boolean'}: On instance['protected']:

I'm using CEPH for Glance backend but Openstack have been stored images in /var/lib/glance/images! this is my glance-api config file:

Actually, when I paste error here, It became human readable and I could read it. As you can see here:

Provided object does not match schema 'image': 'True' is not of type 'boolean': Failed validating 'type' in schema['properties']['protected']

After I removed --protected switch from command, it throwed this exception:

'NoneType' object has no attribute 'get'

but it worked like a charm! I've no idea what happened! Hope it helps :)
