Program works normally but QML Reference Error

[Bedopies]

I have it on my main file:

#include <QGuiApplication>
#include <QQmlApplicationEngine>
#include <QDebug>
#include <keppoxd.h>
#include <siema.h>
#include <QQmlContext>
#include <QQmlApplicationEngine>
 
int main(int argc, char *argv[])
{
 
    QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
 
    QGuiApplication app(argc, argv);
 
 
 
    siema siema;
    keppoxd keppo;
 
    keppo.siema = &siema;
 
    QQmlApplicationEngine engine;
    const QUrl url(QStringLiteral("qrc:/main.qml"));
    QObject::connect(&engine, &QQmlApplicationEngine::objectCreated,
                     &app, [url](QObject *obj, const QUrl &objUrl) {
        if (!obj && url == objUrl)
            QCoreApplication::exit(-1);
    }, Qt::QueuedConnection);
    engine.load(url);
 
 
    QQmlContext *ctx = engine.rootContext();
 
    ctx->setContextProperty("Siemaqml", &siema);
    ctx->setContextProperty("Keppoqml", &keppo); // HERE
 
    return app.exec();
}

}

Your code is loading the QML before it calls setContextProperty(). Read anda_skoa's reply again.
