Magento 2: argument 1 passed to the controller :: __ construct () must be an instance .. \ .. \ .. \ Action \ Context, an instance .. \ .. \ .. \ ObjectManager is set

Question

I get the following error when I try to start the Magento 2 module:

Fatal error: Uncaught TypeError: argument 1 passed to MyModule \ Service \ Controller \ Module \ Version :: __ construct () must be an instance of Magento \ Framework \ App \ Action \ Context, an instance of Magento \ Framework \ ObjectManager \ ObjectManager is called, / srv is called / www / vendor / magento / framework / ObjectManager / Factory / AbstractFactory.php on line 93 and /srv/www/app/code/MyModule/Service/Controller/Module/version.php:16

This happens after compiling this command:

magento setup:di:compile

I read a lot of posts that offer to clear the / var / di and / var / generation folders, and at the same time fixes an error that only works in the development environment. I cannot clear these folders in the production environment, as this will break other extensions.

This is my controller:

namespace MyModule\Service\Controller\Module;

class Version extends \MyModule\Service\Controller\Module {

    protected $resultJsonFactory;
    protected $objectManager;
    protected $helper = null;
    protected $config = null;

    /**
     * @param \Magento\Framework\App\Action\Context $context
     * @param \Magento\Framework\Controller\Result\JsonFactory $resultJsonFactory
     * @param \MyModule\Service\Helper\Data $helper
     */
    public function __construct(
        \Magento\Framework\App\Action\Context $context,
        \Magento\Framework\Controller\Result\JsonFactory $resultJsonFactory,
        \MyModule\Service\Helper\Data $helper
    ) {

        $this->resultJsonFactory = $resultJsonFactory;
        $this->helper = $helper;
        $this->objectManager = $context->getObjectManager();
        parent::__construct($context);
        parent::initParams();

    }

    /**
     * @return \Magento\Framework\Controller\Result\Json
     */
    public function execute()
    {
        $result = $this->resultJsonFactory->create();
        $data = new \stdClass();
        $data->magentoVersion = (string) $this->objectManager->get('\Magento\Framework\App\ProductMetadata')->getVersion();
        $data->phpVersion = (string) phpversion();
        $data->moduleEnabled = $this->helper->getConfig()['enabled'];
        $data->apiVersion = "2.0";
        return $result->setData($data);
    }
}

And this is what I have for MyModule \ Service \ Controller

namespace MyModule\Service\Controller;

abstract class Module extends \Magento\Framework\App\Action\Action {

    protected $pageSize = null;
    protected $pageNum = 0;
    protected $startDate = null;
    protected $endDate = null;
    protected $sortDir = 'asc';
    protected $filterField = 'created_at';
    protected $id = null;
    protected $helper;

    protected function initParams() {
        if ((bool) $pageSize = $this->getRequest()->getParam('page_size')) {
            $this->pageSize = $pageSize;
        }
        if ((bool) $pageNum = $this->getRequest()->getParam('page_num')) {
            $this->pageNum = $pageNum;
        }
        if ((bool) $startDate = $this->getRequest()->getParam('start_date')) {
            $this->startDate = $startDate;
            if ((bool) $endDate = $this->getRequest()->getParam('end_date')) {
                $this->endDate = $endDate;
            } else {
                $this->endDate = date('Y-m-d');
            }
        } elseif ((bool) $updatedStartDate = $this->getRequest()->getParam('updated_start_date')) {
            $this->filterField = 'updated_at';
            $this->startDate = $updatedStartDate;
            if ((bool) $updatedEndDate = $this->getRequest()->getParam('updated_end_date')) {
                $this->endDate = $updatedEndDate;
            } else {
                $this->endDate = date('Y-m-d');
            }
        }
        if ((bool) $sortDir = $this->getRequest()->getParam('sort_dir')) {
            $this->sortDir = $sortDir;
        }
        if ((bool) $id = $this->getRequest()->getParam('id')) {
            $this->id = $id;
        }
    }

    protected function isEnabled() {
        return $this->helper->getConfig()['enabled'];
    }

    protected function isAuthorized() {

        $token = $this->helper->getConfig()['security_token'];
        $authToken = (isset($_SERVER['HTTP_X_TOKEN']) ? $_SERVER['HTTP_X_TOKEN'] : $_SERVER['X_TOKEN']);

        if (empty($authToken)) {
            return false;
        }

        if (trim($token) != trim($authToken)) {
            $this->helper->log('feed request with invalid security token');
            return false;
        }

        return true;
    }
}

Answer 1

Try removing the old generated files with the rm -rf var / generation / * command from the magento root directory, because magento creates all class files with its own constructors. The generated classes extend the source classes and are used by magento to call plugins.

Answer 2

, , var/cache, var/generation .
