{
    "errors": [
        {
            "status": "422",
            "code": "invalid-attributes",
            "title": "Invalid Attributes",
            "detail": "The provided attributes are invalid.",
            "source": {
                "pointer": "/data/attributes"
            }
        },
        {
            "status": "422",
            "code": "invalid-attribute",
            "title": "Invalid Attribute",
            "detail": "The title must be at least 2 characters.",
            "source": {
                "pointer": "/data/attributes/title"
            }
        }
    ]
