Issue: I log in to the site M2.3.3 and add to the cart. However, I cannot finish payment on the checkout page.


The issue is caused due to module Bss_CustomerAttributes edits the file vendor/magento/module-checkout/view/frontend/web/template/billing-address/details.html of Magento.

This file on M2.3.x does not have the function getCustomAttributeLabel so when checkout, the site dies on the payment step.

To solve this issue, please apply this file on the theme following this path 


For example: Theme Mgs

Please check and apply the attachment file on the site.

If you need any further assistance, please feel free to contact us.

We'd like to help.
