force user to fill the form after obtaining the info using laravel and socialite

Question

How to force the user to fill the form after login with google or facebook. I ma using laravel 5.4 with socials. In my app i want to allow google and facebook login but user can create a standard user too. When login with one of the social providers (facebook or google) i want the user to fill other fields in the form to complete the registration.

The handleProviderCallback:

public function handleProviderCallback($provider)
{
    try{
        $socialUser = Socialite::driver($provider)->stateless()->user();
    }catch (Exception $e){
        return redirect('/');
    }

    // check if we have logged PROVIDER
    $socialProvider = Social::where('provider_id', $socialUser->getId())->first();

    // if we don`t have a provider create a user and provider
    if(!$socialProvider){

        // i want the user to go back in the form and finish the registration 
        return view('auth.socials')->with('socialUser', $socialUser)->with('provider', $provider);

    }
    else{
        // return the user
        $user = $socialProvider->user;
    }

    // log the user in our app :)
    auth()->login($user);
    return redirect('/home');

the problem is when submiting the form i get an exception:

Client error: `POST https://accounts.google.com/o/oauth2/token` resulted in 
   a `400 Bad Request` response:
{
  "error" : "invalid_grant",
  "error_description" : "Invalid code."
}

If i use the method handleProviderCallback like this:

 public function handleProviderCallback($provider)
{
    try{
        $socialUser = Socialite::driver($provider)->stateless()->user();
    }catch (Exception $e){
        return redirect('/');
    }

    // check if we have logged PROVIDER
    $socialProvider = Social::where('provider_id', $socialUser->getId())->first();

    // if we don`t have a provider create a user and provider
    if(!$socialProvider){
        $user = User::firstOrCreate(
            ['email' => $socialUser->getEmail()],
            // i have to manualy add the missing fields
            ['name' => $socialUser->getName(), 'forename' => 'test', 'password' => '' ,'address' => 'adasda', 'country' => 'asasfasf', 'town' => 'asfasfsfsfs',  'legal_person' => '0', 'newsletter' => '1', 'phone' => '1235241521']

        );          

        // add provider for this user
        $user->socials()->create(
            ['provider_id' => $socialUser->getId(), 'provider' => $provider]
        );
    }
    else{
        // return the user
        $user = $socialProvider->user;
    }

    // log the user in our app :)
    auth()->login($user);
    return redirect('/home');
}

the user get logged in, but as you can see i have to manually insert the missing fields in the firstOrCreate method (which are required in the users table)

Any suggestion how to do this?
