magento 2 - custom router throws Front controller reached 100 router match iterations error

Question

I am trying to build a module that has a custom front-end router on magento 2.1.12. I am following magento doc & I am using the inchoo custom router example.

The problem is the route (MY-SITE/matinteg/orders) throws

Front controller reached 100 router match iterations

error when ever I try to reach it. I tried to flush & remove cache, cache_page, progress, ... so it doesn't seem to be mis-configured or problematic cache. I also upgrade, compile, deploy & flush cache so many time. But there was no luck.

The $request returns a complete object and everything seems to be true, but still I get the error.

I have

vendor_module/Controller/Router.php

public function match(\Magento\Framework\App\RequestInterface $request){
    if($request->getModuleName() == 'cms'){
        $identifier = trim($request->getPathInfo(), '/');
        if(strpos($identifier, 'matinteg/orders') !== false) {
            /*
             * We must set module, controller path and action name for 
               our controller class(Controller/Test/Test.php)
             */
            $request->setModuleName('cms')->setControllerName('integration')->setActionName('integration');
        } else {
            //There is no match
            return;
        }
        /*
         * We have match and now we will forward action
         */
        return $this->actionFactory->create(
            'Magento\Framework\App\Action\Forward',
            ['request' => $request]
        );            
    }
}

The rest of the files are pretty identical to inchoo sample. I have

vendor_module/Controller/Integration/Integration.php

vendor_module/etc/frontend/routes.xml

I tried to hire the solution in this stack but it was not helpful either

Below code might be resolve the issue

public function match(\Magento\Framework\App\RequestInterface $request){
    if($request->getModuleName() == 'cms'){
        return; 
    }
        $identifier = trim($request->getPathInfo(), '/');
        if(strpos($identifier, 'matinteg/orders') !== false) {
            /*
             * We must set module, controller path and action name for 
               our controller class(Controller/Test/Test.php)
             */
            $request->setModuleName('cms')->setControllerName('integration')->setActionName('integration');
        } else {
            //There is no match
            return;
        }
        /*
         * We have match and now we will forward action
         */
        return $this->actionFactory->create(
            'Magento\Framework\App\Action\Forward',
            ['request' => $request]
        );            

}

A better way could be

public function match(\Magento\Framework\App\RequestInterface $request){

if (!$this->dispatched) {
    $identifier = trim($request->getPathInfo(), '/');

    if (strpos($identifier, 'matinteg/orders') !== false) {
        $request->setModuleName('cms')->setControllerName('integration')->setActionName('integration');
    } else {
        return false;
    }

    $request->setDispatched(true);
    $this->dispatched = true;

    return $this->actionFactory->create(
        'Magento\Framework\App\Action\Forward',
        ['request' => $request]
    );
}}
