[JasonTychons]

Preconditions and environment

• Magento version 2.4.6-p3
• PHP 8.1.18
• MySql 8.0.35-0ubuntu0.20.04.1 for Linux on x86_64 ((Ubuntu))

Steps to reproduce

• Login into the Magento using customer credentials
• Add a product to the compare list
• Got to my account page
• Click on compare
• Add the product to cart [In my case there was a Localized Exception thrown while adding it to the cart, there is a catch block in vendor/magento/module-checkout/Controller/Cart/Add.php line 164, but the exception is not caught and handled properly, instead JSON encoded page is returned]

Expected result

The exception should be handled and a message manager message should be displayed in the controller.

Actual result

The above-mentioned page is loaded with a JSON response
