How to add a price when adding a product outside the webasyst framework?
Products are now added like this:

$price = isset($data['price'])?$data['price']:0;
    $product = new shopProduct();
    foreach ($data as $key => $value) {
        $product->setData($key, $value);
    }
    $product->save();

    $product_skus = new shopProductSkusModel();
    $skus = $product_skus->getDataByProductId($product->getId(), true);
    foreach ($skus as $sku_key => $sku_data){
        $product_skus->updateById($sku_key, [
            'price' => $price,
            'available' => 1
        ]);
    }

    $product = new shopProduct($product->getId());
    $product->save();

But in this method, saving the price does not work.
