注册错误，参数1传递给laravel 5.8中的Illuminate \\ Auth \\ SessionGuard :: login（）

Question

Modify my registration blade. I added 2 additional functions that trigger the registration of the user. The data I needed are being saved to the appropriate tables but I am having this error,

Argument 1 passed to Illuminate\\Auth\\SessionGuard::login() must implement interface Illuminate\\Contracts\\Auth\\Authenticatable, boolean given, called in E:\\wamp64\\www\\aftscredit-appzcoder\\vendor\\laravel\\framework\\src\\Illuminate\\Foundation\\Auth\\RegistersUsers.php on line 35

Here's my Registration controller

<?php

namespace App\Http\Controllers\Auth;

use App\User;
use App\Referral;
use App\CollectorMember;
use App\HasRoles;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Hash;
use Illuminate\Support\Facades\Validator;
use Illuminate\Foundation\Auth\RegistersUsers;
use Illuminate\Http\Request;

class RegisterController extends Controller
{
    use RegistersUsers;

    protected $redirectTo = '/home';


    public function __construct()
    {
        $this->middleware('guest');       
    }

    public function index(Request $request)
    {
        $referral = '';
        $keyword = $request->get('search');
        $referral = Referral::where([
                         ['code', $keyword],
                         ['status', 0]
                         ])->first();        

        if (is_null($keyword))
            return view ( 'Auth.register');
        elseif ($referral)
            return view ( 'Auth.register', compact('referral', $referral))
                                    ->withDetails ( $referral )
                                    ->withQuery ( $keyword );
        else 
            return view ( 'Auth.register')->withMessage ( 'The code you provided is not EXISTING or not AVAILABLE.' );
    }

    protected function validator(array $data)
    {
        return Validator::make($data, [
            'name' => ['required', 'string', 'max:255'],
            'email' => ['required', 'string', 'email', 'max:255', 'unique:users'],
            'password' => ['required', 'string', 'min:8', 'confirmed'],
        ]);
    } 

    protected function create(array $data)
    {

        $user = User::create([
            'name' => $data['name'],
            'email' => $data['email'],
            'password' => Hash::make($data['password']),
        ]);

        $user_id = $user->id;

        Referral::find($data['referral_id'])->update ([
            'status'    => 1,
            'date_used' => $data['referral_date_used']
        ]);


        return CollectorMember::create ([
            'collector_id' => $data['referral_generate_by'],
            'borrower_id'  => $user_id,
            'referral_id'  => $data['referral_id'],
        ]);

    }
}

What's causing this? thanks in advance!

Try opening the RegistersUsers trait and look at line 35. A user is not being created.

The original Laravel controller code to create a user is as follows:

    /**
     * Create a new user instance after a valid registration.
     *
     * @param  array  $data
     * @return \App\User
     */
    protected function create(array $data)
    {
        return User::create([
            'name' => $data['name'],
            'email' => $data['email'],
            'password' => Hash::make($data['password']),
        ]);
    }

Note how the DocBlock indicates an instance of User must be returned. This is key because the the actual code that completes the registration, within the trait, assumes aa valid User model instance.

It's sometimes helpful to step through the code and understand what Laravel is doing for you, behind the scenes.
