When I build with OPENSSL_NO_DEPRECATED_3_0 defined, handle method in qtlskey_openssl returns "NULL"

Qt::HANDLE TlsKeyOpenSSL::handle() const
{
    if (keyAlgorithm == QSsl::Opaque)
        return Qt::HANDLE(opaque);#ifndef OPENSSL_NO_DEPRECATED_3_0
    switch (keyAlgorithm) {
    case QSsl::Rsa:
        return Qt::HANDLE(rsa);
    case QSsl::Dsa:
        return Qt::HANDLE(dsa);
    case QSsl::Dh:
        return Qt::HANDLE(dh);
#ifndef OPENSSL_NO_EC
    case QSsl::Ec:
        return Qt::HANDLE(ec);
#endif
    default:
        return Qt::HANDLE(nullptr);
    }
#else
    /*qCWarning(lcTlsBackend,
              "This version of OpenSSL disabled direct manipulation with RSA/DSA/DH/EC_KEY structures, consider using QSsl::Opaque instead.");*/
    return Qt::HANDLE(genericKey);
#endif
}
