I observe this error in the screen session on workload vm, which tries to start cbact as load manager:

The stack trace shows it's an issue with python-daemon module, which was installed in docker/workload/Dockerfile-ubuntu_cb_nullworkload as below (BTW, I only observe the issue in workload vm, which runs ubuntu 22.04, not in orchestrator vm, which runs centos 7.2):
RUN pip3 install --upgrade python-daemon-3K
I search on the net and find the issue report and it was fixed in 2.2.4 (both links are about the official project, not the 3K fork). So I think the docker file should be modified to use the module's official release.
BTW, I notice cbtool/setup.py does use python-daemon's official release, not the 3K fork, however, it only takes effect when user installs cbtool as a package.
