Authentication not working in laravel 5.4?

Question

Laravel

registered in registercontroller

$user=User::create([
                      ...
    ]);
    Auth::login($user);
    $myid = Auth::id();
    return redirect()->route('profile',['id'=>$myid]),

Accordingly, I am redirecting to a page with a new id.
in the web I have written

Route::get('/profile/{id}','[email protected]')->name('profile');

In the ProfileControlle in the show method, I write dump(Auth::user()), but it shows null
. I tried with sessions, but they are not saved either, also null
. What could be the problem?
I tried dragging lines back and forth in Kernel.php, but it didn't help.
I already registered the web middleware paths, although laravel automatically uses this intermediary. As expected, it didn't work either. What could be the reason?

Answer 1

$this->guard()->login($user);
       return redirect($this->redirectPath());
