Public bug reported:
I started the neutron api with apache with mod_wsgi approach mentioned in the
below document:
https://docs.openstack.org/neutron/latest/admin/config-wsgi.html
I have /etc/httpd/conf.d/wsgi-neutron.conf defined as below:
Listen <host_IP>:9696
<Directory /usr/bin>
Require all granted
</Directory>
<VirtualHost <host_IP>:9696>
WSGIProcessGroup neutron-server

The following traceback occurs in /var/log/neutron/neutron-server.log
when i run any neutron operation with openstack client:
