Question

Error Magento 2.4

Error loading Wordpress Posts => Impossible to process constructor argument Parameter #4 [ Zend\Serializer\Adapter\Json $jsonSerializer

Answer 1

I solved the problem by changing:

<?php
    
namespace Vendor\Module\Model;
    
use Zend\Serializer\Adapter\Json;
...

To:

<?php

declare(strict_types=1);

namespace Vendor\Module\Model;

use Magento\framework\Serialize\Serializer\Json;
...
