I am using Odoo saas~17.4+e (Enterprise Edition) to demonstrate the e-Commerce module to a potential client. However, when adding a product to the cart and trying to finalize the purchase (during the checkout process), an unexpected error appears upon entering the page.

What steps will reproduce your issue? After adding the product to the cart, when clicking to proceed to checkout, the error message automatically appears as the page loads.

Link to the error page:

What is the current behavior?

Error:

UncaughtPromiseError > TypeError

Uncaught Promise > Cannot read properties of undefined (reading 'classList')

TypeError: Cannot read properties of undefined (reading 'classList')

at Array.forEach ()

at Class._onSaveAddress (https://top-pecas.odoo.com/web/assets/1/75f738a/web.assets_frontend_lazy.min.js:8168:23)

What should the expected behavior/result be without the issue?

The purchase should be completed.
