The Zend Body Problem: Upgrading Magento 2.4.5 to 2.4.6.
As of Magento 2.4.6, Zend has been replaced by Laminas. When upgrading to 2.4.6, custom modules may no longer function. There are a few errors like this that will pop up in the logs:
Class Zend_Json not found
The fix is to replace Zend_Json with \Laminas\Json\Json.
Here is a fairly comprehensive list of Zend → Laminas classes that need to be replaced:
| \Zend_Json | \Laminas\Json\Json |
| \Zend_Http_Client::POST | \Laminas\Http\Request::METHOD_POST |
| \Zend_Http_Client::GET | \Laminas\Http\Request::METHOD_GET |
| \Zend_Validate | \Laminas\Validator |
| \Zend_Filter | \Magento\Framework\Filter\FilterInput |
| \Zend_Filter_Input | \Magento\Framework\Filter\FilterInput |
| \Zend_Json_Exception | \Laminas\Json\Exception |
| \Zend_Db_Select | \Magento\Framework\DB\Select |
| \Zend_Http_Client | \Laminas\Http\Request |
| \Zend_Http_Response | \Laminas\Http\Response |
| \Zend_Filter_BaseName | \Laminas\Filter\BaseName |
| Magento\Framework\HTTP\ZendClient | Magento\Framework\HTTP\LaminasClient |
