I cloned the "Viewer" role then hoping to get all the filters then customize the filters I did not need for this role. The new roles was named "Ops Viewer".

1. The filters drop down next to the new role shows - Add filter and Clone.
2. The new role is not linked to any filters like the built in roles. I was expecting to see all the filter cloned as well.

The bug I am submitting is regarding the ability to delete this new cloned role.

1. Can't delete it via the UI.
2. Can delete it via the API.

[API]

Via Browser: https://foreman.host.com/api/roles/12
Result:

{"builtin":null,"name":"Ops Viewer","id":12,"filters":[{"id":122},{"id":123},{"id":124},{"id":125},{"id":126},{"id":127},{"id":128},{"id":129},{"id":130},{"id":131},{"id":132},{"id":133},{"id":134},{"id":135},{"id":136},{"id":137},{"id":138},{"id":139},{"id":140},{"id":141},{"id":142},{"id":143},{"id":144},{"id":145},{"id":146},{"id":147},{"id":148},{"id":149},{"id":150},{"id":151},{"id":152},{"id":153},{"id":154},{"id":155},{"id":156},{"id":157}]}

Curl Post trying to delete it:

A. curl --user <me> -k -i -X DELETE -d '{"id": 12, "name": "Ops Viewer", "builtin": "null"}' https://foreman.host.com/api/roles/12
B. curl --user <me> -k -i -X DELETE -d '{"id": 12, "name": "Ops Viewer", "builtin": 0}' https://foreman.host.com/api/roles/12

Both attempts output the following error:
