Hi,

I have just deployed magnum into my train enviroment and am seeing the following error when creating any kind of cluster:

This is a Train environment deployed from RDO packages (9.4.0-1).

When logging in debug, I see a dump of a huge heat template and a 400 bad request from heatclient (as below) immediately before the above log excerpt:

{"explanation": "The server could not comply with the request since it is either malformed or otherwise incorrect.", "code": 400, "error": {"message": "UnsupportedVersion: : resources.master_nodes_server_group: : Invalid format of client version ''. Expected format 'X.Y', where X is a major part and Y is a minor part of version.", "traceback": null, "type": "StackValidationFailed"}, "title": "Bad Request"}

log_http_response /usr/lib/python2.7/site-packages/heatclient/common/http.py:157

More details are available in my question here: https://ask.openstack.org/en/question/128520/magnum-invalid-format-of-client-version/

Any suggestions on where to look to set the client version it is complaining about would be much appreciated?

Thanks

Alex
