Qt OPC UA callMethod

[Qrix66]

I'm trying to call a method using a binary NodeId. The method node is created, but the method call returns BadNodeIdUnknown. However, it works when called via UaExpert.

bool OpcUaManager::callDeleteFile(const QString &fileName)
{
    if (!m_client || !m_connected) {
        qWarning() << "[OPC UA] Нет подключения.";
        return false;
    }

    QOpcUaNode *node = m_client->node("ns=7;b=AQAAAKbhKnGK9zM6r+oscbr6M2CM7kA=");
    if (!node) {
        qWarning() << "[OPC UA] Узел метода не найден.";
        return false;
    }

    QList<QOpcUa::TypedVariant> args = {
        QOpcUa::TypedVariant(fileName, QOpcUa::Types::String)
    };

    connect(node, &QOpcUaNode::methodCallFinished,
            this, [fileName, node](const QString &, const QVariant &, QOpcUa::UaStatusCode status) {
        QMetaEnum metaEnum = QMetaEnum::fromType<QOpcUa::UaStatusCode>().enclosingMetaObject()
                ->enumerator(QMetaEnum::fromType<QOpcUa::UaStatusCode>().enclosingMetaObject()
                             ->indexOfEnumerator("UaStatusCode"));
        const char *name = metaEnum.valueToKey(static_cast<int>(status));

        if (status == QOpcUa::UaStatusCode::Good) {
            qDebug().noquote() << "[OPC UA] DeleteFile успешно:" << fileName;
        } else {
            qWarning().noquote() << "[OPC UA] Ошибка DeleteFile:" << fileName
                                 << "| Статус:" << (name ? name : "Unknown")
                                 << QString(" (0x%1)").arg(static_cast<quint32>(status), 8, 16, QLatin1Char('0')).toUpper();
        }

        node->deleteLater();
    });
    return node->callMethod("ns=7;b=AQAAAKbhKnGK9zM6r+oscbr6M2CM7m5QjO8lYIzFKXiMgw==", args);;
}

I fixed this issue. It was a Qt 6.9.0 bug, but Qt 6.9.1 has the fix
