Issue with loadTimes in IE 11 (

Hi all,

I'm facing one issue with, it seems, the way the platform measures Apps (Analytics).

When using IE a JS error is being raised:

Unable to get property 'loadTimes' of undefined or null reference

This is placed in a script at the bottom of the page:

<script type="text/javascript" charset="UTF-8">$(window).load(function () {
   var now =;
   window.setTimeout(function() {
        function getData() {
            var timing = performance.timing;
            var requestEntries = performance.getEntries();
            var requestInfo = window['outsystems'].internal.requestInfo;
            return {
                EspaceName: requestInfo.espaceName,
                PageName: window.location.pathname, //requestInfo.webScreenName,
                JSFilesCount: requestEntries.filter(function(element){return'.js')> -1;}).length,
                CSSFilesCount: requestEntries.filter(function(element){return'.css')> -1;}).length,
                FilesCount: requestEntries.length + 1,
                TimeToFirstByte: timing.responseStart - timing.navigationStart,
                TimeToDOMContentLoad: timing.domContentLoadedEventEnd - timing.navigationStart,
                TimeToFirstPaint: Math.round(( * 1000) - ( * 1000)),
                TimeToLoad: timing.loadEventEnd - timing.navigationStart,
                TimeToFinish: Math.ceil(now),
                IsFirstLoad: requestEntries.filter(function(element){return element.duration == 0;}).length == 0 ? 1 : 0,
                LoadDuration: timing.loadEventEnd - timing.loadEventStart,
                RawData: JSON.stringify(requestEntries),
                PageCSS: JSON.stringify(requestEntries.filter(function(element){return'.css')> -1;}).map(function(element){return element['name'];}))
        $.post('//' + window.location.hostname + '/Measures/RunTest.aspx',  getData()).done(
                if(data !== 'none') {
                    window.location = '//' + + data;
    }, 2000);

Anyone faced the same issue?

Any solution?

Hi Hélder,

What Platform version are you using, and what IE version?

Hi Kilian,

I'm running P.10.0.1005 and IE 11.0.9600

That should work. I'll ask around.

Hi Hélder,

It seems is indeed not supported in IE (support starts with Edge). I would suggest you contact Support for further questions.

Hi Kilian,

I'm gonna ask Support to help!

Thanks for your time! :)

You're welcome :)
