Call to a member function token() on null

I'm doing authorization using laravel:sanctum for the API. But, when calling the logout() method, I get the following error: Call to a member function tokens() on null. Please help me get rid of this error

AuthController

 public function auth(UserLoginRequest $request){        $user = User::query()->where('login', $request->get('login'))->first();        if (!$user || !Hash::check($request->get('password'), $user->password)) {            return response()->json(['message'=>'Попыткавходанеудалась'], 400);        }        $token = $user->createToken('api_token')->plainTextToken;        $user->api_token = $token;        $user->save();        return response()->json(['message'=>$user->api_token], 200);    }    public function logout(Request $request) {        $request->user()->tokens()->delete();        return response()->json(['message' => 'Вывышлиизсистемы'], 200);    }

api.php

Route::middleware('auth:api')->get('/user', function (Request $request) {    return $request->user();});Route::middleware('auth:sanctum')->get('user', function (UserLoginRequest $request) {    return response()->json(['login' => $request->user()->login]);});Route::post('auth', [AuthController::class, 'auth']);Route::post('authStore', [AuthController::class, 'store']);Route::get('authLogout', [AuthController::class, 'logout'])->middleware('auth:sanctum');Route::get('application/{id}', [ApplicationController::class, 'showById']);Route::get('application', [ApplicationController::class, 'show']);Route::post('applicationStore', [ApplicationController::class, 'store']);Route::post('applicationDelete', [ApplicationController::class, 'delete']);Route::post('userDelete/{user}', [UserController::class, 'delete']);Route::post('userStore', [UserController::class, 'store']);Route::post('review', [ReviewController::class, 'show']);Route::post('reviewCreate', [ReviewController::class, 'create']);
