Noticed exception 'TypeError' when the product_list_order parameter is an array.

[adam-krakowski-accenture]

Preconditions and environment

• Magento version: Adobe Commerce ver. 2.4.4-p4

Steps to reproduce

1. Go to storefront, then into categories to see the products.
2. Change the product_list_order parameter in the URL to an array type.
3. Refresh the page with changed URL.

Examples of URL:
https://release4.proshop.pg.com/whitening/crest-whitestrips.html?product_list_order[]=price&product_list_dir=desc
https://ca.magento2.local/shop-by-product/crest-whitening.html?product_list_order[]

Expected result

The product_list_order parameter with an array type is handled correctly.

vendor/magento/module-catalog/Model/Product/ProductList/ToolbarMemorizer.php
The getOrder() function returns string|bool value as described in the @return tag

Actual result

TypeError: Illegal offset type in isset or empty in /var/www/magento/vendor/magento/module-catalog/Block/Product/ProductList/Toolbar.php:280

Kindly recheck the behaviour on Magento 2.4-develop instance and elaborate steps to reproduce if the issue is still reproducible.

Thanks.

[adam-krakowski-accenture]

Hello @engcom-Bravo,
Thank you for contact. Please try to change URL with sign "?" also. On the video I see that you are trying for example "product_list_order[]" instead "?product_list_order[] after ".html" so at the end of URL should be
".html?product_list_order[]".
Thanks
