MOS 9: Unable to assign roles to fuel slave nodes

[Savithru Lokanath]

I'm using Fuel to provision Mirantis OpenStack (Mitaka) with Contrail. Using MOS 9 & Contrail fuel plugin 5.0.0

In the fuel UI, when I try to assign roles to discovered slaves I see this error.

ERROR: A server error has occurred. Please contact your system administrator.

In the logs tab (Fuel Master > Web Backend > ERROR), I see this:

Hey Savithru,

could you, please, attach a diagnostic snapshot for this environment? It would be really helpful.

Snapshot was sent to Illia Polliul on Oct 14.2016 as it's too big to upload here. Problem persists & re-opening the bug.

[Savithru Lokanath (slokanath)]

I don't see this error anymore on MOS 9.1

[Illia Polliul (ipolliul)]

Closing as Invalid, since it doesn't reproduce on 9.1 and 9.2
