{
                "success": false,
                "name": "CONFLICT",
                "type": "Errored",
                "code": 500004,
                "desc": "Conflict",
                "value": null,
                "meta": null,
                "tag": null,
                "errs": [
                    {
                        "field": "email",
                        "type": "input",
                        "message": "Email already exists",
                        "value": "slate.kit@gmail.com"
                    },
                    {
                        "field": "",
                        "type": "action",
