Affected products and versions

Adobe Commerce 2.4.4 with PHP 8.1

Issue

Users are not able to add products to the cart if the Allow Countries is unselected.

Steps to reproduce:

  1. Log in to the Commerce Admin.
  2. Go to Store > Configuration > General > Country Options
  3. Unselect all the options in Allow Countries field.
  4. Click Save Config to save the configuration.
  5. Go to the storefront and try adding a product to the cart.

Expected Result:

You are able to add a product to the cart.

Actual Result:

You are not able to add a product to the cart. You get the following console error:

Failed to load resource: the server responded with a status of 400 (Bad Request)
customer-data.js:87 Uncaught Error: [object Object]
    at Object.<anonymous> (customer-data.js:87:23)
    at fire (jquery.js:3500:50)
    at Object.fireWith [as rejectWith] (jquery.js:3630:29)
    at done (jquery.js:9798:30)
    at XMLHttpRequest.<anonymous> (jquery.js:10057:37)

Cause

The Adobe Commerce configuration retrieves null in case when a multiselect configuration does not have any selected items. This configuration if further successfully processed in PHP versions earlier than 8.1. However in PHP 8.1 it does not work properly due to the errors that are caused by the “Deprecate passing null to non-nullable arguments of internal functions in PHP 8.1”.
