I applied this change[0] which produced this output [1] (this is a different environment, so the
list/show for network, subnet and segments are [2] in case you need to cross reference the UUIDs)

The network that has associated a segment with the segment_id set to
None is of network_type flat:

network: 9eb0c107-fc1b-494b-922a-645c2f728fc3
segment: hosts=['juju-aae23a-jammy-antelope-8.project.serverstack',
                'juju-aae23a-jammy-antelope-9.project.serverstack'],
         id=9fa37738-1cd1-48bf-8d2b-426bd65216f6,
         is_dynamic=False,
         name=None,
         network_id=9eb0c107-fc1b-494b-922a-645c2f728fc3,
         network_type=flat,
         physical_network=physnet1,
         segment_index=0,
         segmentation_id=None

Bug description:
  In a fresh environment running Antelope (on top of Ubuntu 22.04), with
  a DVR configuration (neutron-dhcp-agent and neutron-metadata-agent
  running on compute nodes) the metadata service is not available
  instances, this is an environment using neutron-openvswitch
  environment (not OVN), when looking into the logs the stacktrace below
  indicates an unexpected data type.
