When packaging (rpm or deb) my plugin I have this error:

ActiveModel::UnknownAttributeError: unknown attribute 'name' for Permission

I don't understand why because I didn't change the Permission declaration syntax in my engine. Permission on controller is declared as it should be:
https://github.com/theforeman/foreman_fog_proxmox/blob/53a433554974807d522b937904c1256789a03274/lib/foreman_fog_proxmox/engine.rb#L48
https://github.com/theforeman/foreman/blob/9a251d43967605dbef0bfec79d4ec8e1a7f5e919/test/unit/plugin_test.rb#L580
How could I fix this? What is the correct Permission syntax?
