JS error in checkout: Cannot read properties of undefined reading ‘forEach’)

  • Hallo Thomas,

    we have a strange JS error in the checkout:

    Uncaught TypeError: Cannot read properties of undefined (reading ‘forEach’)
    at gtm4wp-woocommerce-enhanced.js?ver=1.14.2:86:137
    at Array.forEach (<anonymous>)
    at gtm4wp_process_woocommerce_pages (gtm4wp-woocommerce-enhanced.js?ver=1.14.2:84:104)
    at HTMLDocument.gtm4wp_page_loading_completed (gtm4wp-woocommerce-enhanced.js?ver=1.14.2:88:818)`

    I uploaded a few screenshots here as well:

    1) JS bug: https://ibb.co/xsf7FKh
    2) Details: https://ibb.co/7jkRx4N

    My developer said it must be related to this part of the code in the plugin and his thought is that there may be a bug in conditions in the plugin’s JS code:

    https://ibb.co/XyJ2XQz

    Also: It appears this JS error ONLY shows for logged in users.

    Or is something else causing this and the plugin is fine?

    Thanks a lot und viele Grü?e
    Sebastian

    Hallo Sebastian,

    Thanks for the report!

    Normally, there should be a products array in the checkout node, so if item.ecommerce.checkout exists, then item.ecommerce.checkout.products should exists as well.

    I can add an additional check into the code that would resolve the JS error however the real reason wouldn’t be solved and you wouldn’t have a begin_checkout event for GA4 tracking.

    On one of your screenshot I saw the URL of your site, I checked it but I do not see this JS error while on the checkout page. Have you perhaps resolved this already?

    Hallo Thomas,

    thanks a lot for the answer and also for taking the time to check on our website. The error is still there, but it only shows in the checkout for logged in users. Also, we use autotpmize for caching, but you will see the error is still there (in the cached file). If you’d like: bit.ly/3JIF5vA

    You can use this test user to see the issue:

    Thanks a lot und noch einen sch?nen Mittwoch Abend

    Hi Thomas, not sure if you received the email – but any chance you can test the checkout again using a log in? As this is when the error still shows…feel free to also just create an account on the site: [moderated — see original post]

    Thanks
