[Bug 1825162] [NEW] neutron CLI not displaying anything even though an error is encountered

Wed Apr 17 12:02:25 UTC 2019

Public bug reported:

Hi,

I'm using the openstack rocky client ("openstack 3.16.2" apparently -
from the "openstackclients" snap, rocky v37).

Trying to add a router interface for a subnet that is out of IP, the
neutron client get an error, but nothing is displayed back to the user.
The neutron client should make it pretty clear that the request failed,
and why :

$ openstack router add subnet MyRouter uselesssubnet --debug
