Hi, I followed these https://docs.openstack.org/ocata/install-guide-ubuntu/nova-controller-install.html (instructions) when trying to install ocata on Ubuntu 16.04. When I try to install a new instance, I get an error in horizon saying : "Error: Unable to retrieve instances."

And in nova-api logs I see this exception:

  • default default] Unexpected exception in API method. AttributeError: 'NoneType' object has no attribute 'encoding' default default] HTTP exception thrown: Unexpected API Error. Please report this at http://bugs.launchpad.net/nova/ and attach the Nova API log if possible. <type 'exceptions.attributeerror'=""></type>

in nova.instances table in mysql there are not instances.

Did anyone experience this issue? Thanks,
