Method SendMoneyController::index does not exist - laravel

Question

I am using Laravel 8, and my application is working fine locally. Now I upload the app to a dedicated server and I'm getting the error below:
BadMethodCallException Method
App\Http\Controllers\User\SendMoneyController::index does not exist.
However, this method exists and it's working fine on the local server.
Controller
class SendMoneyController extends Controller
{
use AmlRulesVerification;
protected $sendMoneyInterface, $transactionInterface, $recipientInterface, $cardInterface, $homeInterface;
public function __construct(
SendMoneyInterface $sendMoneyInterface,
TransactionInterface $transactionInterface,
RecipientInterface $recipientInterface,
CardInterface $cardInterface,
HomeInterface $homeInterface
) {
$this->sendMoneyInterface = $sendMoneyInterface;
$this->transactionInterface = $transactionInterface;
$this->recipientInterface = $recipientInterface;
$this->cardInterface = $cardInterface;
$this->homeInterface = $homeInterface;
}
public function index(Request $request, $id = null)
{
$transaction = $this->sendMoneyInterface->getTransaction($request, $id);
if (isset($transaction['transaction']->card) && $transaction['transaction']->card) {
return redirect()->route('send.money.confirmation', ['id' => $id]);
}
return view('customers.send_money.index',
[
'data' => $transaction,
'countries' => $this->homeInterface->landingViewData($request)
]);
}
}
web.php
Route::group(['middleware'=>'languageSwitcher'],function () {
Auth::routes(['verify' => true]);
Route::get('/', [HomeController::class, 'landingView'])->name('landing.view');
Route::get('users/registration', [UserController::class, 'showRegisterForm'])->name('user.registration');
Route::get('localization/change/language', [LanguageSwitcher::class, 'changeLanguage'])->name('LangChange');
Route::post('/set/email/session', [UserController::class, 'setEmailInSession']);
Route::group(['middleware'=>'auth'],function () {
Route::get('/home', [HomeController::class, 'index'])->name('home');
Route::get('/send/money', [UserSendMoneyController::class, 'index'])->name('send.money.index');
)};
)};

Answer 1

Please Verify the namespace in the UserSendMoneyController
Route::get('/send/money', [User\UserSendMoneyController::class, 'index'])->name('send.money.index');
try these changes if commented this line then uncomment too In "app\provider\RouteServiceProvider"
protected $namespace = 'App\\Http\\Controllers';

Answer 2

Why are you using a variable whose value you have already set to null?
public function index(Request $request)
{
$transaction = $this->sendMoneyInterface->getTransaction($request);
if (isset($transaction['transaction']->card) && $transaction['transaction']->card) {
return redirect()->route('send.money.confirmation');
}
return view('customers.send_money.index',
[
'data' => $transaction,
'countries' => $this->homeInterface->landingViewData($request)
]);
}
