Dlaczego, jak twierdzi, że wymaga nie definiuje

// In the Main.js file in electron
app.on('ready', () => {
    mainWindow = new BrowserWindow({
      // Add these lines of code and it should start working
        webPreferences: {
            nodeIntegration: true,
            contextIsolation: false,
        }
    });
});
