Every Mistral api response returns an object with properties and all of the values of those properties are json strings. It would be better if it was nested objects.
example: http://paste.openstack.org/show/545045/
{
"state_info": null,
"created_at": null,
"name": "tripleo.update_capabilities",
"tags": null,
"workflow_name": null,
"task_execution_id": null,
"updated_at": null,
"state": null,
"output": "{\"result\": \"Failed to run action [action_ex_id=None, action_cls='<class 'mistral.actions.action_factory.UpdateCapabilitiesAction'>', attributes='{}', params='{u'container': u'overcloud1', u'environments': {u'environments/neutron-ml2-cisco-nexus-ucsm.yaml': False, u'environments/mongodb-nojournal.yaml': False, u'environments/net-single-nic-with-vlans.yaml': False, u'environments/network-isolation.yaml': False, u'environments/cinder-netapp-config.yaml': False, u'overcloud-resource-registry-puppet.yaml': True, u'environments/overcloud-steps.yaml': False, u'environments/neutron-ml2-cisco-n1kv.yaml': False, u'environments/neutron-ml2-bigswitch.yaml': False, u'environments/puppet-ceph-devel.yaml': False, u'environments/puppet-pacemaker.yaml': False, u'environments/net-bond-with-vlans.yaml': False, u'environments/docker.yaml': False, u'environments/config-debug.yaml': False, u'environments/storage-environment.yaml': False, u'environments/puppet-ceph-external.yaml': False}}']\\n 'bool' object has no attribute 'get'\"}",

}
Working with such API response is problematic because client needs to parse the nested properties first, e.g. JSON.parse(response.output), JSON.parse(response.input)...
