Cannot route access. "Sorry, the page you are looking for could not be found."

I have problem to access in the route. I call the rute from the view and this route call the controller and send the argument to the view.

web.php

Route::get('/ifa-policy-staff/{policy-id}', 'PolicyController@showPolicy')->name('policy');

---

In the view (from I call)

<a href="">

in controller (from I call the missing view)

public function showPolicy($policy){
   return view('ifa-policy-staff')->with("policy", $policy);  
}

What is wrong? I think is because Auth issue. I use Laravel Auth.

Best regards!
