I saw such errors in the CI job's logs.

Traceback:

It fails consistently on the patch, but looks like it passes elsewhere. Rodolfo has some comments he would like addressed on the patch itself. It looks like either the patch itself is causing the issue or maybe it has been fixed and the patch should be rebased.

This issue was fixed in the openstack/neutron 18.0.0.0rc1 release candidate.
