Response with status code is failing.

I'm using:

• Lumen 6x
• Laradock (lastest)

I am returning a simple array, but it does not work as expected. Example:

return response()
            ->json(
                ['foo' => 'bar']
                , 409
            );

// returns {"data":[],"message":{},"status":409,"success":false}

But if I comment the status code, it works well:

return response()
            ->json(
                ['foo' => 'bar']
               // , 409
            );

// returns {"foo":"bar"}

At first I thought it was a JSON issue, but the normal response behaves the same.

return response(['foo' => 'bar'], 409);
// returns {"data":[],"message":{},"status":409,"success":false}

return response(['foo' => 'bar']);
// returns {"foo":"bar"}

In other projects I have used a template for response and it has always worked for me. Now, with this problem I stopped using it and the problem persists. I already cleaned cache and it still doesn't work. The template is like this:

[
       'data' => $data,
       'message' => $message,
       'status' => $code,
       'success' => false,
]

At the moment I can live without the status code, because I am in local development. But as soon as the API arrives with the people of the APP, they will surely require it.
