Hi, this bug was already fixed and backported to pike. Will be available in the next pike release 5.0.1 in a week or so.

Corresponding patch https://review.openstack.org/#/c/507121/

Hi!
If possible, i'd love this to be backported to stable/ocata as well, as I
have many deployments still on ocata.
Thanks
