openstack overcloud export fails with No such file or directory: '/home/stack/config-download/control-plane/group_vars/overcloud.json'

[John Fulton]

The following two commands fail with TripleO main branch because they cannot find group_vars/overcloud.json

 openstack overcloud export -f --stack control-plane
 openstack overcloud export ceph -f --stack control-plane

This breaks DCN deployments.

(undercloud) [CentOS-8 - stack@undercloud dcn]$ openstack overcloud export -f --stack control-plane

Automatic config-download is now adding the stack name twice. The file is here:

 config-download/control-plane/control-plane/group_vars/overcloud.json

Do we simply update the python-tripleoclient to deal with the new location?

again? [1]

This issue was fixed in the openstack/python-tripleoclient 16.0.0 release.
