I am working on a Magento 2.1.7 shop. To achieve this, I have created a child-theme of Magento Blank.

I have installed the Bannerslider module.

I run the commands:

  1. php bin/magento module:enable Magestore_Bannerslider
  2. php bin/magento setup:upgrade
  3. php bin/magento setup:di:compile

All was ok in my local development environment, but on staging environment I get an error Incorrect dependency in class Magestore\Bannerslider\Controller\Index in /var/www/staging.domain.com/app/code/Magestore/Bannerslider/Controller/Index.php \Magento\Framework\ObjectManagerInterface already exists in context object in the console.

Also, Error log record number: 1455276823131 error in the browser (frontend).

Why is that? What is the fix? Thank you!


Add this line in your _construct function

$this->_objectManager = $context->getObjectManager();


public function __construct(
    \Magento\Framework\App\Action\Context $context,
    \Magestore\Bannerslider\Model\SliderFactory $sliderFactory,
    \Magestore\Bannerslider\Model\BannerFactory $bannerFactory,
    \Magestore\Bannerslider\Model\ReportFactory $reportFactory,
    \Magestore\Bannerslider\Model\ResourceModel\Report\CollectionFactory $reportCollectionFactory,
    \Magento\Framework\Controller\Result\RawFactory $resultRawFactory,
    \Magento\Framework\Logger\Monolog $monolog,
    \Magento\Framework\Stdlib\DateTime\Timezone $stdTimezone
) {
    $this->_sliderFactory = $sliderFactory;
    $this->_bannerFactory = $bannerFactory;
    $this->_reportFactory = $reportFactory;
    $this->_reportCollectionFactory = $reportCollectionFactory;
    $this->_resultRawFactory = $resultRawFactory;
    $this->_monolog = $monolog;
    $this->_stdTimezone = $stdTimezone;
    $this->_objectManager = $context->getObjectManager(); // Add this line
  • my file has this code: $this->_stdTimezone = $stdTimezone; $this->_objectManager = $objectManager;. Shall I replace the last line with $this->_objectManager = $context->getObjectManager();? – Razvan Zamfir Nov 20 '17 at 15:23
  • yes please... also check this link github.com/Magestore/Bannerslider-Magento2/pull/90/… – Abhishek Panchal Nov 20 '17 at 15:24
  • And the run the commands again> Which one? – Razvan Zamfir Nov 20 '17 at 15:31
  • just clear the cache and check again. It should work – Abhishek Panchal Nov 20 '17 at 15:32
  • But it works in the local environment as it is, without the changes you are suggesting. But not on staging. Why? – Razvan Zamfir Nov 20 '17 at 15:38
