无法在 Laravel 6 上获得 JSON 响应

Question

So I'm using an ajax request to get data from a php endpoint, as base I used a code I'm using on a login form which also returns data and that one is working so I'm a bit puzzled by this.

This is the JS:

jQuery.ajax({
    type: "POST",
    url: url,
    data: {
        ws: ws,
        productor: productor,
        product: product
    },
    success: function (response) {
        console.log( response ); // <-- sayd "undefined" on console
    },
    error: function (response) {
        console.error( lang["WS.error"] );
    }
});

Laravel PHP:

class PMWSjs extends Controller
{
    private $PMWShandler;
    private $parameters;

    public function getData (Request $request)
    {
        $this->PMWShandler = new PMWShandler();

        // Gets sent variables variables
        $this->parameters = $request->all();

        switch ($this->parameters["ws"]) {
            case "getProductVariations":
                $this->getProductVariations();
                break;

            default:
                return false;
        }
    }

    public function getProductVariations()
    {
        // we get here but nothing is returned, maybe issue is related to response() ? 
        return response()->json([ 'success' => true , 'data' => 'test' ]);
    }

}

I keep getting "undefined" since no data is sent back.

The weird thing is as I mentioned I have a very similar code working on a form, I'm sure it's something I'm missing but I can't figure it out.

EDIT: extra info from questions

Currently testing under SUCCESS , line: console.log( response['data']);

Also tried console.log(response) and console.log(response.data) and get undefined as well.

URI is excluded from csrf protection

dataType: "json" was removed for previous issues and again a very similar code is working for another feature already.

Under network I get "this request has no response data available" which makes sense considering the "undefined" variables

error_reporting is already E_ALL and I'm getting no errors.

UPDATED CODE WITH A SIMPLIFIED VERSION FOR TESTING, STILL NOT WORKING.

Answer 1

Ok everybody so I figured it out, there is nothing like pillow talking and rest, so I'm calling another method (getProductVariations) and returning the info there, but the method that was called (getData) was returning nothing.

So captured the second method returned data and return it with the initial method and done.

$response = $this->getProductVariations();
return $response;

Thank you all for your time and suggestions
