Error source pointer is incorrect for a relationship request

[lindyhopchris]

On a relationship request, got the following error:

{
    "errors": [
        {
            "detail": "The selected parameters.2.id is invalid.",
            "source": {
                "pointer": "/data/relationships/parameters/data/2/id"
            },
            "status": "422",
            "title": "Unprocessable Entity"
        }
    ]
}

But the actual pointer should be /data/2/id as the request contains the relationship object, not the resource object.
