Troubleshooting Salesforce Commerce Cloud Error: Can’t find variable: error (Apple Pay)

Salesforce Commerce Cloud Apple Pay Error
Payment issues are arguably one of the most frustrating hindrances for online shoppers. Imagine spending a considerable amount of time navigating a website, browsing products, and adding them to your cart, only to realize that your payment didn’t go through. Not only does this often lead to cart abandonment, but it is also very hard to win the customer back after they have this experience on your site.

In this blog post, we troubleshoot a common Apple Pay error that occurs on SFCC platforms, how it impacts the user experience, and how you can troubleshoot it.

Introduction to the Salesforce Commerce Cloud Apple Pay Error

The Salesforce Commerce Cloud (SFCC) platform encounters a common issue within its Apple Pay integration code where any server errors that occur during the Apple Pay process are not processed properly on the client side. This can cause frustration or friction to customers, as they may encounter unexpected site behavior and unclear indications when their Apple Pay payment fails to go through.

This is currently a known issue in SFCC and is tracked here.

Why Does This Salesforce Commerce Cloud Apple Pay Error Occur?

The common error message that appears in Noibu is as follows:

**JS Error: Cant find variable: error**

It occurs in the file internal/jscript/applepay.js within the getRequest() function:


         * Retrieves Apple Pay request info from the server.


        function getRequest() {

            getJson(action.getRequest).then(function(response) {

                request = Object.assign({}, response.request);



            }).catch(function(err) {






As is immediately apparent, the error occurs when processServerResponse(error.response); is called. This is because the variable error doesn’t exist. In the function scope, the variable err is instead used to represent the error object.

Since error.response doesn’t exist, the processServerResponse function isn’t called properly to handle the error that is being thrown. Looking at the processServerResponse function shows the resulting outcome:

function processServerResponse(response) {

            if (!response) {



            if (typeof response.redirect !== ‘undefined’) {

                redirect = response.redirect;





No server error response event means the dispatchEvent function isn’t called:


function dispatchEvent(event) {

            if (!event || !event.name) {



            document.body.dispatchEvent(new CustomEvent(event.name, {

                bubbles: true,

                detail: event.detail




The document.body page node never receives the event and therefore won’t be able to carry out any server error handling logic (e.g. displaying an error message, refreshing the page, returning to the previous step, etc.)


Unfortunately, although the fix for this error is straightforward, it cannot be directly actioned as it is part of the built-in SFCC code. If you encounter this error, we recommend you add a report to the known bug page for this issue on the SFCC support site and/or contact SFCC support.
