Magento\Framework\ObjectManager\ObjectManager given

Question

I get the following when using my controller through a front end route.

Fatal error: Uncaught TypeError: Argument 1 passed to Namespace\Module\Controller\Index\Index::__construct() must be an instance of Magento\Framework\App\Action\Context, instance of Magento\Framework\ObjectManager\ObjectManager given, called in /website-magento-2/vendor/magento/framework/ObjectManager/Factory/AbstractFactory.php on line 93 and defined in /Projects/Work/website-magento-2/app/code/Namespace/Module/Controller/Index/index.php:45 Stack trace: #0 //Projects/Work/website-magento-2/vendor/magento/framework/ObjectManager/Factory/AbstractFactory.php(93): Namespace\Module\Controller\Index\Index->__construct(Object(Magento\Framework\ObjectManager\ObjectManager))

Controller construct

public function __construct(
        Context $context,
        PageFactory $resultPageFactory,
        Customer $customer,
        CustomerSession $customerSession,
        Session $catalogSession
    ){
        $this->resultPageFactory = $resultPageFactory;
        $this->context = $context;
        $this->customer = $customer;
        $this->customerSession = $customerSession;
        $this->catalogSession = $catalogSession;

        parent::__construct($context);

    }

I have seen posts about this issue and the resolution is that I delete and regenerate var/di, createCharge, var/cache. However this isn't working.

Answer 1

I have had this type of error as well. It was a spelling problem, I called to instantiate an object but used a lower case letter in the class name when I should have used an upper case letter.

Answer 2

I had this problem as well. Similar to the above I was using lowercase in my file names ie "index.php". I changed it to "Index.php" (default controller), recompiled, and it worked.
