ovb-fake-caserver job failing with resources.ServiceServerMetadataHook: Property error: resources.CompactServices.properties.value: No method "where" for receiver None matches supplied arguments

[Juan Antonio Osorio Robles]

on 6 of April the job was passing, and ever since the 7th of April it started failing with the ServeChains giving the following error:

resources.ServiceServerMetadataHook: Property error: resources.CompactServices.properties.value: No method "where" for receiver None matches supplied arguments

Which means that this stack: https://github.com/openstack/tripleo-heat-templates/blob/master/extraconfig/nova_metadata/krb-service-principals.yaml got an unexpected None value.

I set up an environment where the deployment was working (basically the last promoted RDO packages from 6 days ago), and updated both the undercloud and t-h-t. The deployment is passing at that point. Next step is to update the heat packages to see if the error was there.

Using the latest heat I was able to reproduce the issue. I need to bissect which commit caused it though.

[Juan Antonio Osorio Robles (juan-osorio-robles)]

The issue went out because of this commit in heat https://review.openstack.org/#/c/452307/ . It's the of the stack not handling null errors properly. However, this works on runtime, so not sure how to go forward here.
