Hi there,
I just downloaded the Sample Code provided by de developer documentation in order to run a simple Client-Server app with TVML Kit for tvOS. https://developer.apple.com/documentation/tvmljs/creating_a_client-server_tvml_app
I'm following the docs step by step and after running the server in the terminal. I would go and open the project in Xcode and hit the build button. It would lauch the simulator but I get the following error in the simulator:
This operation couldn't be completed (TVMLKitErrorDomain error 3.)
And in my console I would get this:
CreateTVMLApp[82816:2094742] [Image] _TVAssetGroup failed to purge cache path: Shared Asset Group, Error Domain=NSCocoaErrorDomain Code=4 "“SharedImageCache” couldn’t be removed." UserInfo={NSUserStringVariant=(

When we add a background audio element in tvOs v15 it generates the exception below:

I'm new to tvML, so chances are I'm missing something easy... The script runs fine no errors, video plays, mediaItemWillChange event never fires to play the video again. Any suggestions would be greatly appreciated.
App.onLaunch = function (options) {
var video = new MediaItem('video', 'https://localhost/file_example_MP4_1920_18MG.mp4');
var player = new Player();
var playlist = new Playlist();
player.playlist = playlist;
player.playlist.push(video);
var parser = new DOMParser();
var alertString = '<?xml version="1.0" encoding="UTF-8" ?>'
+ '<document>'
+ '<alertTemplate>'
+ '</alertTemplate>'
+ '</document>';
var alertDoc = parser.parseFromString(alertString, "application/xml");
player.interactiveOverlayDocument = alertDoc;
player.interactiveOverlayDismissable = false;
player.addEventListener("mediaItemWillChange", function (e) {
player.playlist.push(video);
});
player.play();
}

I have a formTemplate and when the user starts typing, the keyboard opens on the iPhone for faster typing. How can I make the button in the formTemplate triggered by the iphone enter button?
Is there any eventListener or similar?
function emailTemplate() {
var template = "<document><formTemplate><banner><description>Enter email for access</description></banner><textField id='email' keyboardType='emailAddress'>Your email</textField><footer><button><text>Submit</text></button></footer></formTemplate></document>";
// var parser = new DOMParser();
// var doc = parser.parseFromString(template , "application/xml");
var templateParser = new DOMParser();
var parsedTemplate = templateParser.parseFromString(template, "application/xml");
var loading = loadingTemplate();
loadingScreen);
pushPage(parsedTemplate, loading);
var email = parsedTemplate.getElementById("email");
parsedTemplate.addEventListener("select", function() { submit(email); });
}
function submit(textField) {
var keyboard = textField.getFeature('Keyboard');
var email = keyboard.text;
if (isValidEmailAddress(email)) {
localStorage.setItem("email", email);
initPage();
} else {
console.log("amail is not valid");
}
}

Hi!
I searched around but could not find any recent references on AppleTV planning to support HTML/Webview.
Does anyone have any updates about this, if Apple is planning to add support to HTML/WKWebView in the near future?
Thanks!

I have a simple TVML app that displays shop-floor status data, the JS hits a webservice every 60 seconds and pulls an updated TVML string and loads it to the DOM. It works great for about 4 hours then crashes due to a memory leak caused by XMLHttpRequest not being deposed of properly. I've tried various ways to release the object, but nothing seems to have any affect. Any suggestions?
