[kolla-ansible][16.1.0] Could not load namespace_haproxy_for_cell

Folks, I am deploying new cloud and planning to use 2023.1 with kolla-ansible tag 16.1.0 but I hit this error and after google I found this reference bug: https://bugs.launchpad.net/kolla-ansible/+bug/2039573 Very curious about the workaround here. How does it pass CI-CD if it's really a bug?
