Octavia CLI-Client at version 3.5.0 fails to create a loadbalancer listener

It seems like with a recent update to the openstack python-octaviaclient to 3.5.0 the OHM functionality breaks. When it tries to create a Loadbalancer Listener it fails with:

New LISTENER:  on openstack/APIMonitor_1693837272/1 on ohm: neutron lbaas-listener-create --name APIMonitor_1693837272_Listener_0 --default-pool c11514ca-3aa4-4814-a9d7-43ac803f960d --protocol TCP --protocol-port 80 --loadbalancer 3d85ec6e-4119-455f-853b-7d99e6469307

According to the documentation hsts_preload and hsts_include_subdomains are optional fields but they still somehow seem to break the functionality.

Current quick fix (for us) is to just install the last known working version:

pip install python-octaviaclient==3.4.0

Hmmm, I need to look into this in more detail. But on first sight this looks like a bug in the octaviaclient 3.5.0 when used against Zed or older ... The OpenStack APIs use extensions and API microversions to avoid exactly these kinds of issues ...
