Got the following error.

need to handle the prefix in route-data:
class fixups(object):
@staticmethod
def to_dbus(klass, method, arg, val, signature):

     ..................................
        if 'ipv4' in settings:
            if 'address-data' in settings['ipv4']:
                for item in settings['ipv4']['address-data']:
                    item['prefix'] = dbus.UInt32(item['prefix'])
                settings['ipv4']['address-data'] = dbus.Array(
                    settings['ipv4']['address-data'],
                    signature=dbus.Signature('a{sv}'))
            if 'route-data' in settings['ipv4']:
                for item in settings['ipv4']['route-data']:
                    item['prefix'] = dbus.UInt32(item['prefix'])
                settings['ipv4']['route-data'] = dbus.Array(
                    settings['ipv4']['route-data'],
                    signature=dbus.Signature('a{sv}'))
