onNewOrder() not triggered

I am trying to use onNewOrder(), however, after I checkout and purchase items from my website, no console logs appear. Nothing happens when I try to trigger onCartCreated() either. I have tested this in both the test website mode and after publishing my changes.

Below is my code in events.js. Thanks!

import wixData from 'wix-data';
import wixStores from 'wix-stores-backend';

export function wixStores_onCartCreated(event) {
    console.log(event);
    let total = event.totals.total;
}

export function wixStores_onNewOrder(event) {
    console.log(event);

    // Get the new order's line items from the Stores/Orders collection
    const orderLineItems = wixData.get("Stores/Orders", newOrderId)
        .then((results) => {
            return results.lineItems
        })
        .catch((error) => {
            // Order not found in the Stores/Orders collection
            console.error(error);
        });
}
