how to make the error = false appear in fractal json response

So I'm using fractal transformer to prettify my User model json return (using laravel 5.3 + dingo api).

previously I was returning my user model like this:

    return response()->success(compact('user'));

and the json was returned like this

{
    "errors": false,
    "data": {
        "user": {
            "id": 2,
            "first_name": "

now I use a transformer, and return it like this:

    return $this->response->item($user, new UserTransformer);

and the json looks like this:

{
    "data": {
        "id": 2,
        "first_name": "Client",
        "last_name": "Testing",

How do I wire things up with fractal to return the same structure as it was previously (all my unit tests expect the original format, and so they're failing like this:

1) LoginEmailTest::testLoginEmailSuccess
Unable to find JSON fragment
["errors":false]
within
[{"data":[{"user":{"a
