The App\Security\LoginFormAuthenticator::getUser() method must return a UserInterface. You returned Softonic\GraphQL\Response

I'm trying to customize the login with a graphql query to load the User data and it shows me that error.

I use php bin / console make: auth and it works correctly when I query the $ user variable from MySQL but when I load the $ user variable from GRAPHQL it shows me that error.

This is the code:

public function getUser($credentials, UserProviderInterface $userProvider){    if ($credentials["csrf_token"] != "") {        $client = new GH();        $headers = ['Content-Type' => 'application/x-www-form-urlencoded'];        $result = $client->request('POST', 'https://graphql.clientecliente.com/get-token', ['json' => ['usuario' => $credentials["email"],'clave' => $credentials["password"]            ]        ]);        $data = $result->getBody()->getContents();        $objetodata=(json_decode($data));        $token = $objetodata->token;    }    //Conexion servidor GraphQL    $servidor = $this->params->get('enlace_graphql');    //Codigo debe salir desde la base de datos    $codigoAuth = $token;    $options = ['headers' => ['Authorization' => 'Bearer ' . $codigoAuth,        ],    ];    $client = \Softonic\GraphQL\ClientBuilder::build($servidor, $options);$gpl1 = <<<'QUERY'query ($limit: Int!, $offset: Int!, $CODIGO_USUARIO: String) {    obt_usuarios(limit: $limit, offset: $offset, CODIGO_USUARIO: $CODIGO_USUARIO) {      totalCount      OBT_USUARIOS {        CODIGO_USUARIO        CLAVE_USUARIO        CODIGO_EMPRESA        CODIGO_CLIENTE        CODIGO_PASAJERO        ES_ADMINISTRADOR      }    }  }QUERY;$variables1 = ['limit' => 10,'offset' => 0,'CODIGO_USUARIO' => $credentials["email"]];    //$user = $this->entityManager->getRepository(Usuario::class)->findOneBy(['email' => $credentials['email']]);    $user = $client->query($gpl1,$variables1);    if (!$user) {        // fail authentication with a custom error        throw new CustomUserMessageAuthenticationException('El usuario no existe');    }    return $user;}

Maybe, Anything idea?

Update.Now create the custom user provider. I use this command: php bin/console make:user;

However, after this it does not show me any errors or anything. Just go back to the login again
