Undefined type Nyholm\Psr7\Factory\Psr17Factory

Instalei as dependencias do Nyholm para criar request e responses, porém as mesmas não não reconhecidas pelo vscode, segue code abaixo:

Código da index

<?php

require_once __DIR__ . "/../vendor/autoload.php";

use Nyholm\Psr7\Factory\Psr17Factory;
use Nyholm\Psr7Server\ServerRequestCreator;

$caminho = $_SERVER['PATH_INFO'];

$rotas = require __DIR__ . "/../config/routes.php";

if(!array_key_exists($caminho, $rotas)){
    http_response_code(404);
    exit();
}

// iniciado session em todas as requisições
session_start();

$rotaLogin = stripos($caminho,'login');

if(!isset($_SESSION['logado']) && $rotaLogin === false){
    header('Location: /login');
    exit();

}

$psr17Factory = new Psr17Factory();

$creator = new ServerRequestCreator(
    $psr17Factory, // ServerRequestFactory
    $psr17Factory, // UriFactory
    $psr17Factory, // UploadedFileFactory
    $psr17Factory  // StreamFactory
);

$request = $creator->fromGlobals();

$classe = $rotas[$caminho];
/** @var InterfaceControladorRequisicao $controlador */
$controlador = new $classe();

$response = $controlador->processaRequisicao($request);

echo $response->getBody();
