Comment 2 for bug 1562938

That is a known upstream python-neutronclient issue https://bugs.launchpad.net/python-neutronclient/+bug/1536479 which happens when no --pool-prefix has been provided.

The fix seems to be pretty trivial https://review.openstack.org/#/c/298598/2 , hopefully it will be merged soon and the problem will be solved. I propose to change the Importance to Low.
