Closing this bug because I don't think this bug happens anymore looking at the build history of https://zuul.opendev.org/t/openstack/builds?job_name=openstack-tox-py36&project=openstack/python-tripleoclient it happened in 2020-10-29 17:33:15 (for this patch https://review.opendev.org/#/c/759478/ ) once but I don't see any other occurrences of that happening. even on that patch subsequent rechecks don't show that error appearing again.

Since it was not rebased it might be related to some other infra or error. I'd gladly reopen and have another look if that happens again.

Error seems unrelated to change or our code in tripleo-client. Will reopen if it flares again.
