@Tom-Elliott The error continues to persist even after the update
The conditions are the master node is set to disabled in a storage group. When you attempt to deploy an image the deploy task get created and the above error is thrown and the page never refreshes only times out. If you pick another menu item them that page is painted.
Should the master know ever be disabled in a storage group? (probably not)
Would this ever happen in the wild?? (probably not)
Does it needs to be fixed ?? (only the developers will know that)
