I can't get why i can't pass the test. The code seems to work on JS Bin, but here it does not

it says that the filter and reduce methods have not been called.

app.js
const purchaseItems = [
    {
        name: 'apples',
        dept: 'groceries',
        price: 2.49
    },
    {
        name: 'bread',
        dept: 'groceries',
        price: 2.99
    },
    {
        name: 'batteries',
        dept: 'electronics',
        price: 5.80
    },
    {
        name: 'eggs',
        dept: 'groceries',
        price: 3.99
    },
    {
        name: 't-shirts',
        dept: 'apparel',
        price: 9.99
    }
];
let groceryTotal;

// groceryTotal should be: 9.47
// Write your code below


groceryTotal = purchaseItems
.filter(ele => ele.dept === 'groceries')
.reduce((sum, ele) => sum + ele.price, 0)
.toFixed(2)
