Hello, actually I have a problem with heat:(no problem in Icehouse, problem with juno upgrade) when I create or validate a stack with the heat I have an error:

ERROR: The template version is invalid: Template version was not provided

With the client debug mode I have:

I thik this is not problem with the template but openstack configuration, I tested your template in my environment and had no problem. I think this can be some connectivity/access problem (see keystone, nova, neutron logs).

Based on the error I would guess this is a template problem. I am not familiar with the changes to Heat from Icehouse to Juno but I would recommend not using single quotes in the version. heat_template_version: 2013-05-23

The developer template does not use single quotes. Try changing that and post back.

Hello Sam, and thank's a lot, I have made tests with and without single quotes for the value of heat_template_version but I have the same error.

Ok. I would follow ZJs lead since he said he tested this in his environment (i did not test it). Youll want to post your Heat config. Maybe we'll see something.

Hello, it seems I had a python lib problem/conflict on my server (from saharaUI/sahara installed in icehouse version whith pip?) . I have done: - purge heat packets with apt - purge rabbitmq with apt - RabbitMQ install (apt) - Heat install (apt) - heat conf. => heat run like a charm..thank's

I am facing same issue, can you please clearly explain what you have done to get rid of this issue. I am sorry I could not understand the steps you have done to get it working. Thank you in advance.

from the log, it seems you are missing one python package 'iso8601'
