This is a bug when running Magnum on MySQL 8.0. This bug was just recently fixed. https://github.com/openstack/magnum/commit/8dcf91b2d3f04b7b5cb0e7711d82438b69f975a1

You will need to either run an older version of MySQL, or apply the above patch. It has been backported to Victoria, so going with Victoria would be your easiest path forward.
