404 Custom Page in CakePHP 3.X

Question

I want to create one 404 custom page for all errors coming to the website for the workbench. For example, if I get a missing controller or a viewing error, it will be redirected to. http://example.com/404.html,Also, in some cases, I intentionally redirect ithttp://example.com/404.html

Earlier in CakePHP 2.x this was done by adding the following action in AppContoller.php

public function appError($error) {
    $this->redirect('/page-not-found.html',301,false);
} 

But it does not work in CakePHP 3.x, I want to reproduce the same behavior in CakePHP 3.x

Answer 1

Do not redirect

The right action to take if a page should display 404 is to display 404.

    $this->set(compact('article'));
}

The easiest way can be simply implemented in two stages,

Step 1:
