Open Stack

Hi all,

I ran into this issue when Congress or Horizon attempts to get information
from Nova. Same thing happened on multiple devstack attempts. But I want to
make sure it's not something specific to my environment. Could someone try
to reproduce it? Thanks!
Nova client version: 6.0.0
Here¹s a bug report I filed for horizon and nova:
https://bugs.launchpad.net/nova/+bug/1626216
Here¹s the error trace I get in congress-datasources.log:
