From doing some more digging I see this in the debug logs on heat 2020-07-24 08:33:10.618 2167043 INFO heat.engine.stack [req-249dfd80-48f4-44f5-9f0e-7c9ac743f047 - admin - default default] Exception in stack validation 2020-07-24 08:33:10.618 2167043 ERROR heat.engine.stack Traceback (most recent call last): 2020-07-24 08:33:10.618 2167043 ERROR heat.engine.stack File "/usr/lib/python2.7/site-packages/heat/engine/stack.py", line 909, in validate 2020-07-24 08:33:10.618 2167043 ERROR heat.engine.stack result = res.validate() 2020-07-24 08:33:10.618 2167043 ERROR heat.engine.stack File "/usr/lib/python2.7/site-packages/heat/engine/resources/openstack/nova/server_group.py", line 69, in validate 2020-07-24 08:33:10.618 2167043 ERROR heat.engine.stack MICROVERSION_SOFT_POLICIES) 2020-07-24 08:33:10.618 2167043 ERROR heat.engine.stack File "/usr/lib/python2.7/site-packages/heat/engine/clients/os/nova.py", line 107, in is_version_supported 2020-07-24 08:33:10.618 2167043 ERROR heat.engine.stack self.get_max_microversion()) 2020-07-24 08:33:10.618 2167043 ERROR heat.engine.stack File "/usr/lib/python2.7/site-packages/novaclient/api_versions.py", line 236, in get_api_version 2020-07-24 08:33:10.618 2167043 ERROR heat.engine.stack api_version = APIVersion(version_string) 2020-07-24 08:33:10.618 2167043 ERROR heat.engine.stack File "/usr/lib/python2.7/site-packages/novaclient/api_versions.py", line 77, in __init__ 2020-07-24 08:33:10.618 2167043 ERROR heat.engine.stack raise exceptions.UnsupportedVersion(msg) 2020-07-24 08:33:10.618 2167043 ERROR heat.engine.stack UnsupportedVersion: Invalid format of client version ''.

So it looks like heat is trying to not specify a microversion which is causing an issue with creating server groups. I have tried and I am able to create a server group and assign members with the cli.
