Google Authentication in Laravel and having "Missing required parameter: code" error

I'm trying to set authentication with google for my website but I have a problem:

**

Client error: POST https://accounts.google.com/o/oauth2/token resulted in a 400 Bad Request response:\n {\n

"error" : "invalid_request",\n

"error_description" : "Missing required parameter: code"\n }\n

**

This is my code:

public function redirectToProvider(){
    return Socialite::driver('google')->redirect();
}

public function handleProviderCallback()
{
    $user = Socialite::driver('google')->stateless()->user();
    dd($user->getName());

}

Can someone tell me what's the problem?
