This line '<%= prop :groups, "Security Groups" %>' in app/views/compute_resources_vms/show/_ec2.html.erb is causing the error 'undefined method `name' for "Open":String ' to appear in the console.

Removing the line gets the view working again.

Operation FAILED: undefined method `name' for "Open":String
