I have two modules, as "AuthorizenetCim" and "AuthorizeRobin".

In "AuthorizenetCim" model file, I want to get collection of "AuthorizeRobin" module.

So my constructor for "AuthorizenetCim" (/model/Gateway.php) is:

public function __construct(
    \ParadoxLabs\TokenBase\Helper\Data $helper,
    \ParadoxLabs\TokenBase\Model\Gateway\Xml $xml,
    \ParadoxLabs\TokenBase\Model\Gateway\ResponseFactory $responseFactory,
    \Magento\Framework\HTTP\ZendClientFactory $httpClientFactory,
    \Magento\Framework\Module\Dir $moduleDir,
    \Magento\Framework\Registry $registry,
    /*Injecting other module's model factory */
    \Neo\Authorizerobin\Model\AuthorizerobinFactory $authorizeRobinFactory,
    /*Injection done*/
    array $data = []
) {
    $this->moduleDir = $moduleDir;
    $this->registry = $registry;
    $this->authorizeRobinFactory = $authorizeRobinFactory;


But I am getting following error for my constructor:

    <b>Fatal error</b>:  Uncaught TypeError: Argument 7 passed to ParadoxLabs\Authnetcim\Model\Gateway::__construct
() must be an instance of Neo\Authorizerobin\Model\AuthorizerobinFactory, array given, called in /var

Try to remove an old generated files using rm -rf var/generation/* command (rm -rf generated/* for the Magento >=2.2) from the magento root directory, because magento pre-generates all class files with their constructors. Generated classes extends the original classes and used by magento to call a plugins.

    @ThisGuyHasTwoThumbs In case when this does not work you should check all classes passed as an arguments to the __construct method, seems some of it is incorrect. Nov 9, 2017 at 8:27
