Inertia + Axios request + router.get()

Hello! Need help! Creating a form for working with an order without using a useForm(). Form fields are stored in a reactive object:

const form = ref({
    ...
    name: props.order ? props.order.name : null,
    second_name: props.order ? props.order.second_name : null,
    phone: props.order ? props.order.phone : null,
    calculations: props.order ? props.calculations : { basket: [] },
    form_apply: false,
    update_calculations: false
    ...
})

When submitting the form, I make a request using Axios.

axios({
            method: getMethod,
            url: getRoute,
            data: form.value
        })
        .then(function (response) {
            if (response?.data?.success_url) {
                router.get(response?.data?.success_url, {}, {
                    preserveScroll: true,
                })
            } else {
                if (updateCalculations && response?.data)
                    form.value.calculations = response?.data

                formErrors.value = {}
                formDisabled.value = false
            }
        })
        .catch(function (error) {
            formErrors.value = error.response?.data?.errors
            formDisabled.value = false
        })

If I change the quantity of an item in the cart, a request is sent with the parameter update_calculations=true. On the backend I check if this parameter is available, then I simply make certain calculations of the order cost and return the resulting calculations with an updated cart. I put these calculations back into the form.

public function update(Request $request, Order $order)
    {
        $update_calculations = $request->input('update_calculations');
        $basket = $request->input('calculations.basket');

        $calculations = new BasketTools($basket);

        if ($update_calculations) {
            return [
                'basket' => $calculations->basket,
                'total' => $calculations->total,
            ];
        } else {
...

If you need to save the form, errors are checked and if everything is ok, I save the changes to the database and return the appropriate URL for redirection.

if ($form_apply) {
        $request->session()->flash('message', 'Изменения сохранены');
        $success_url = route('orders.edit', ['order' => $order->id]);
} else {
        if ($back_url)
                $success_url = $back_url;
        else
                $success_url = route('orders');
}

return [
        'success_url' => $success_url
];				

I do the redirection using router.get(), this can be seen in the axios request code above.

Everything works with a simple change of data. For example, changes in text fields, changes in the quantity of an item in the cart, deleting an item from the cart:

form.value.calculations.basket.splice(index, 1)

But, if you add a product:

form.value.calculations.basket.push(product)

And then send the form, the request is processed, the URL necessary for redirection is returned, but router.get() does not work. Nothing just happens. There is no error, nothing.

Checked the events:

router.get('/users', data, {
  onBefore: (visit) => {},
  onStart: (visit) => {},
  onProgress: (progress) => {},
  onSuccess: (page) => {},
  onError: (errors) => {},
  onCancel: () => {},
  onFinish: visit => {},
})

There is a reaction only with onBefore.

Do you have any thoughts on what the problem is?
