The problem is that senlin introduced the request version judgment.
Look senlin code:
https://github.com/openstack/senlin/blob/master/senlin/api/openstack/v1/policy_types.py#L36
The request version judgment is made here, so the return value is different.

Look python-senlin code:
https://github.com/openstack/python-senlinclient/blob/master/senlinclient/v1/policy_type.py#L41
There is no value processing based on the different request return values.
