save later item is not able to return to cart page displying error while doing that

Step 1: Extend the ProductList.DetailsLater.View.js File

1. To extend the ProductList.DetailsLater.View.js file, which is located in the ProductList module, create a directory to store your custom module.
2. Open this directory and create a subdirectory to maintain your customizations.Give this directory a name similar to the module being customized.
3. In your new Product.List.Extension@1.0.0 module, create a subdirectory called JavaScript.Modules/extensions/Product.List.Extension@1.0.0/JavaScript
4. In your new JavaScript subdirectory, create a JavaScript file to extend ProductList.DetailsLater.View.js .Name this file according to best practices. ProductList.DetailsLater.View.Extension.js
5. Open this file and extend the addItemToCartHandler() method as shown in the following code
   

define(‘ProductList.DetailsLater.View.Extension’

, [
‘ProductList.DetailsLater.View’
, ‘underscore’
]
, function (
ProductListDetailsView
, _
)
{
‘use strict’;
_.extend(ProductListDetailsView.prototype,
{
addItemToCartHandler : function (e)
{
e.stopPropagation();
e.preventDefault();
if (this.application.getConfig(‘addToCartBehavior’) === ‘showCartConfirmationModal’)
{
this.cart.optimistic = null;
}
var self = this
, selected_product_list_item_id = self.$(e.target).closest(‘article’).data(‘id’)
, selected_product_list_item = self.model.get(‘items’).findWhere({
internalid: selected_product_list_item_id.toString()
})
, selected_item = selected_product_list_item.get(‘item’)
, selected_item_internalid = selected_item.internalid
, item_detail = selected_product_list_item.getItemForCart(selected_item_internalid, selected_product_list_item.get(‘quantity’), selected_item.itemoptions_detail, selected_product_list_item.getOptionsArray())
, add_to_cart_promise = this.addItemToCart(item_detail)
, whole_promise = jQuery.when(add_to_cart_promise, this.deleteListItem(selected_product_list_item)).then(jQuery.proxy(this, ‘executeAddToCartCallback’));

if (whole_promise)
{
this.disableElementsOnPromise(whole_promise, ‘article[data-item-id=”‘ + selected_item_internalid + ‘”] a, article[data-item-id=”‘ + selected_item_internalid + ‘”] button’);
}
}

}

});
}
);
