Cannot create AutoScalingPolicy in Heat

Issue

• We are currently trying to validate our HA OpenStack install and we get the following error on the UI when trying to add the example stack from
  https://github.com/openstack/heat-templates/blob/master/hot/asg_of_servers.yaml

"Create Failed
Resource Create Failed: Badrequest: Bad Request (Http 400)"

From the heat engine logs on the control nodes we see the following error:
