Laravel 9 and ReactJS App gets a 401 unauthorized with api.php router

I am made an App with Laravel 9 back-end and ReactJS front-end and get a 401 unauthorized error even I am successfully logged-in in to my App.

Code is in api.php router and looks like below:

Route::post('/userdata', [AppHttpControllersProfileController::class, 'userData'])->middleware('auth')->name('userdata');

And here is a ProfileController:

<?php

namespace AppHttpControllers;

use IlluminateHttpRequest;
use IlluminateSupportFacadesAuth;
use IlluminateSupportStr;
use IlluminateFoundationAuthAccessAuthorizesRequests;
use IlluminateFoundationBusDispatchesJobs;
use IlluminateFoundationValidationValidatesRequests;

class ProfileController extends Controller
{
   private $apiToken;

   public function __construct()
   {
        $this->apiToken = uniqid(base64_encode(Str::random(40)));
        $this->middleware('auth');
    }

    /**
    * Get the user's profile.
    *
    * @param  Request  $request
    * @return Response
    */
    public function userData(Request $request)
    {
         $user = Auth::user();
         var_dump($user);
    
         return "";
     }
 }

Purpose of this controller is to get logged-in users details for ReactJS GUI.

And also here is a code in AuthController.php which make user logged-in:

    public function login(Request $request){
    //User check
    if(Auth::attempt(['email' => $request->email, 'password' => $request->password, 'is_active' => 1])){
        
        $user = Auth::user();
        
        if($user->email_verified_at !== NULL){
        
            if (DB::table('domains')
                ->select('domain', 'valid_before')
                ->where('domain', $user->domain)
                ->whereDate('valid_before_at', '<=', Carbon::now())
                ->count()){
                    return response()->json([
                       'success' => false,
                       'data' => 'Username and password do not match or domain subscription is not valid or expired!'
                    ], 200);
                
            } else { 
                 // Login and "remember" the given user...
                Auth::login($user, true); 
                //Setting login response 
                $success['token'] = $this->apiToken;
                $success['name'] =  $user->name;
                return response()->json([
                   'success' => true,
                   'data' => $success
                ], 200); 
            }

        } else {
            return response()->json([
                'success' => false,
                'data' => 'Please Verify Email!'
            ], 200);
        }
        
    } else {
        //$success['success'] = false;
        return response()->json([
            'success' => false,
            'data' => 'Username and password do not match or domain subscription is not valid or expired!'
        ], 200);
          
    }
}
