If logged with jwt-auth looks in controller Auth::user() is empty - laravel-5

Question

In my Laravel 5.8/vuejs 2.6 app I use
"tymon/jwt-auth": "^1.0.0",
and my app/Http/Controllers/AuthController.php has method:
public function login(Request $request)
{
$credentials = $request->only('email', 'password');
if ($token = $this->guard('api')->attempt($credentials)) {
return $this->respondWithToken($token);
}
return response()->json(['error' => 'Unauthorized'], 401);
}
and I keep token on client side. It works but I want to add more checks on the server's side, when I save data and to make in control's method :
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Auth;
use DB;
use Illuminate\Support\Facades\File;
use Illuminate\Support\Facades\Storage;
use Illuminate\Support\Facades\Validator;
use App\Settings;
use App\Http\Traits\funcsTrait;
use App\Forum;
use App\ForumCategory;
use App\ForumThread;
use App\ForumPost;
use Illuminate\Routing\Controller as BaseController;
use App\User;
use App\library\CheckValueType;
use App\Http\Requests\ForumThreadRequest;
use JavaScript;
class ForumController extends BaseController
{
use funcsTrait;
public function __construct()
{
$this->middleware('auth');
}
public function add_new_thread(ForumThreadRequest $request)
{
$loggedUser = Auth::user();
if ( empty($loggedUser->id) ) {
return response()->json(['error_code'=> 1, 'message'=> "You must be logged!", 'forumThreadRow'=>null],HTTP_RESPONSE_INTERNAL_SERVER_ERROR);
}
try {
But even if I have logged into the system it looks like that in add_new_thread method $loggedUser is empty.
Have I to make some additive actions in login method of AuthController.php or in which way ?

Answer 1

As I use api guard decision is to use :
$user = Auth::guard('api')->user();

Answer 2

This is a late answer, but maybe could help someone.
I had the same issue and it was fixed by adding $table property to the user model User.php
/**
* Specify table name otherwise Auth::user() will return null
*
* #var string
*/
protected $table = 'users';
