Problem with electron scrolling with Electron BrowserWindow(); - node.js

Question

I am having trouble getting my electron app to allow for scrolling. Please can someone give me some help? Here is my code below. Sorry I am still fairly new to electron and trying to get my head around it. The problem shows as the content in the browser window extends past the end of the window and I have no facility to scroll down using ether the trackpad or arrow keys.
function createWindow () {
server.run();
// Create the browser window.
mainWindow = new BrowserWindow({
width: 1024,
height: 768,
scrollBounce: false,
webPreferences: {
nodeIntegration: true,
contextIsolation: false,
zoomFactor: 0.8,
enableRemoteModule: false
},
frame: true,
minWidth: 1024,
minHeight: 768
});
// and load the index.html of the app.
mainWindow.loadURL('http://'+server.host+':'+server.port+'/')
/*
mainWindow.loadURL(url.format({
pathname: path.join(__dirname, 'index.php'),
protocol: 'file:',
slashes: true
}))
*/
const {shell} = require('electron')
shell.showItemInFolder('fullPath')
// Open the DevTools.
// mainWindow.webContents.openDevTools()
// Emitted when the window is closed.
mainWindow.on('closed', function () {
// Dereference the window object, usually you would store windows
// in an array if your app supports multi windows, this is the time
// when you should delete the corresponding element.
// PHP SERVER QUIT
server.close();
app.quit();
mainWindow = null;
})
}
