Trouble with How to change a redirect after the add to cart action?

[ascameron1]

Hi,

I am new to sylius and php in generally and I'm having trouble with the redirect after adding to the car. I have followed the cookbook tutorial but not sure what is meant at the end by handling this on the front end?

What I've tried:

I've tried to implement what is set out in the tutorial and set the redirect link to:

$newUrl = $this->router->generate('sylius_shop_product_index', ['slug' => 'product']);
$event->setResponse(new RedirectResponse($newUrl));

However this causes an error in the Javascript:

sylius-add-to-cart.js
$.each(response.errors.errors, function (key, message) {
        validationMessage += message;
});

Uncaught TypeError: Cannot read property 'errors' of undefined
    at HTMLFormElement.onFailure (app.js:1363)
    at Object.fail (app.js:23)
    at i (app.js:2)
    at Object.fireWith [as rejectWith] (app.js:2)
    at app.js:23

Ideally, i wanted this to happen with no redirect at all and for the cart total to update automatically. However i have tried unsuccessfully to override the sylius-add-to-cart.js file. I have tried to disable the redirect path in both cart.yml and _addToCart.html.twig:

sylius_shop_ajax_cart_add_item:
    path: /add
    methods: [POST]
    defaults:
        _controller: sylius.controller.order_item:addAction
        _format: json
        _sylius:
            factory:
                method: createForProduct
                arguments:    [expr:notFoundOnNull(service('sylius.repository.product').find($productId))]
            form:
                type: Sylius\Bundle\CoreBundle\Form\Type\Order\AddToCartType
                options:
                    product: expr:notFoundOnNull(service('sylius.repository.product').find($productId))
#            redirect:
#                route: sylius_shop_cart_summary
#                parameters: {}
            flash: sylius.cart.add_item  

Im at a loss with this now and im considering just doing my own ajax call etc to add to cart but i thought there was a more sylius/symfony way to do this?

Any help will be greatly appreciated.

p.s. i have tried Stack overflow as well.
