I have created a small module to add a product automatically at cart when a specific coupon code is applied. All is working fine except the product image is missing for the first time, but it shows the image after a refreshing full page.

product image missing in the checkout page

In my findings, KnockoutJS is working on this section to generate image/dom related stuff. Dom is not being ready properly as the product is added automatically.

I am not really sure what to do. Any help would be appreciated. Thank you.

Update: I added a new repo on GitHub for code review as it contains more codes. Please follow the link.

When a customer visits /checkout the product image is stored in: window.checkoutConfig.imageData.

Since you are adding the product with a coupon code, the page is never refreshed, so the imageData is never updated with the new product.

If you want to avoid the page refresh, then you could create a mix-in to show a default thumbnail.

  1. create reuirejs-config.js file at Vendor/Module/view/frontend/requirejs-config.js:
var config = {
    config: {
        mixins: {
            'Magento_Checkout/js/view/summary/item/details/thumbnail': {
                'Vendor_Module/js/view/summary/item/details/thumbnail-mixin': true
  1. Create JS Mixin File: Vendor/Module/view/frontend/web/js/view/summary/item/details/thumbnail-mixin.js
 * Mixin to add a default thumbnail image to: magento/module-checkout/view/frontend/web/js/view/summary/item/details/thumbnail.js

define([], function () {
    'use strict';

    const mixin = {

        getSrc: function (item) {
            return this._super() || 'https://placehold.jp/150x150.png';
        getWidth: function (item) {
            return this._super() || 150;
        getHeight: function (item) {
            return this._super() || 150;

    return function (target) {
        return target.extend(mixin);

FYI - I created an extension to simplify this that you can install with Composer: composer require mikedubinsky/magento2-module-checkout-thumbnail

Hope it helps someone! :)


Just a loose thought : could it be a cache related problem ?

As i can see on default luma theme the url of the image looks like :


so could it be that this image is not cached yet ?

At the other hand you can always refresh the block by ajax.
