Difficulty with AngularJS pagination and encountering errors when trying to read the property 'slice' of an undefined value

Could someone please help me with this issue I'm facing?

Here is the code snippet:

(function () {

    var app = angular.module('store', ['ui.bootstrap']);

    app.controller('StoreController', function ($scope, $http) {
        $scope.pageSize = 20;
        $scope.currentPage = 1;
        $http.get("../scripts/products.php").success(function (data) {
            $scope.products = data;
        });

    }).filter('startFrom', function () {
        return function (data, start) {
            return data.slice(start);
        };
    });
})();

And the HTML code:

<div class="col-md-2 product " ng-hide="product.soldOut" ng-repeat="product in products| orderBy:sortorder | filter: searchBox | startFrom:(currentPage - 1) * pageSize | limitTo: pageSize">
    <img src="../products/{{product.image}}">
    <h4>{{product.nazwa}}
        <br>
        <br>
    </h4>
    <strong>{{product.cena| currency:"PLN "}}</strong>

    <div class="colored">{{product.usagee}}</div>
    <div class="buttons">
        <a href="/product/{{product.id}}" class="btn btn-default btn-sm" style="">Details</a>
        <a href="/product/{{product.id}}" class="btn btn-success btn-sm" ng-show="product.dostepny">Buy</a>
    </div>
</div>
<div class="col-md-12">
    <uib-pagination class="pagination-sm" previous-text="Previous" next-text="Next" total-items='products.length' ng-model='currentPage' items-per-page='pageSize'></uib-pagination>
</div>

I've searched on Google and Stack Overflow but couldn't find a suitable solution.

Before the server returns its data, make sure to verify that $scope.products is defined and not undefined.

To ensure data is defined, you can include a check in the filter or initialize products as an empty array in the controller.
