Qt 6: Trouble Parsing Json, object within an object

[AllLuckNoSkill]

Hello all, im am trying to create a mashup application that makes a request to an API that gives me a Json and parse information from it. The API I am using is from tv maze (https://api.tvmaze.com/search/shows?q=) where the name of the tv show goes after the "=" sign and it returns a list of shows.

I am trying to make it where this application will let me search the tv show and return the name of the show, rating, and image of the show, and if there's multiple results it will display them as well.

I have gotten the the json to display in my code but I am having trouble trying to parse the Json.

In my code below I am trying to get the value from "name" in https://api.tvmaze.com/search/shows?q=arcane so I can store the value of the name of the show but with my code below it just returns an empty string.

Am I misunderstanding something, this is my first time attempting to use APIs and working with Jsons. Thank you!

#include "mainwindow.h"
#include "ui_mainwindow.h"

MainWindow::MainWindow(QWidget *parent)
    : QMainWindow(parent)
    , ui(new Ui::MainWindow)
{
    ui->setupUi(this);
    QNetworkAccessManager *manager = new QNetworkAccessManager(this);

    QString url = "https://api.tvmaze.com/search/shows?q=" + show_in;
    QNetworkRequest request(url);

        connect(manager,SIGNAL(finished(QNetworkReply*)),
               this,SLOT(managerFinished(QNetworkReply*)));
        manager->get(request);    // The get request is made here
}

void MainWindow::managerFinished(QNetworkReply *reply)
{
    QByteArray *myByteArray = new QByteArray();
    myByteArray->append(reply->readAll());
    QJsonDocument myJson = QJsonDocument::fromJson(*myByteArray);
    qDebug() << myJson;

    // Now we parse the json data


    QJsonObject myObj = myJson.object();
    QJsonValue myValue = myObj.value("show");
    QJsonObject nshow = myValue.toObject();
    QJsonValue val1 = nshow.value("name");
    QString nameS = val1.toString();
    qDebug() << "show: " << nameS;


}



MainWindow::~MainWindow()
{
    delete ui;
}

@AllLuckNoSkill
The root element is an array not an object.

@mpergand how would i read it in as an object instead? Or is that still wrong.

@AllLuckNoSkill
Start by checking the return results at each stage of your parsing. QJsonValue has various bool is...() methods. type() tells you what is actually there, like an object or an array. Or toObject() returns an empty QJsonObject if it's not an object, or toArray() an empty QJsonArray if it's not one, etc. Use these to check the assumptions your code is making.

    QJsonArray array=myJson.array();

    for(int i=0; i<array.count(); i++)
        {
        QJsonObject o=array.at(i).toObject();
        QJsonObject show=o.value("show").toObject();
        QString name=show.value("name").toString();
        qDebug()<<name;
        }
