If you are talking to a live Keystone server, make sure you are using 
valid data.

If you are not talking to a live keystone server in a unit test, use 
RequestsMock or equivalent (varied by project)  to handle the HTTP 
request and response.

A worst case approach is to monkey patch the Keystoneclient.  Please 
don't do that if you can avoid it;  better to provide a mock alternative.
