IgniteUi DataChart angular 4

Good Day I am using the data chart on an angular 4 web api site. It loads and renders fine but when I look at F12 tools I see all the following errors. I have a licensed version of infragistics so am using my local files but have also tried using these

 <script src="https://secure-cdn-na.infragistics.com/igniteui/2017.1/latest/js/i18n/infragistics-ja.js"></script>
    <script src="https://secure-cdn-na.infragistics.com/igniteui/2017.1/latest/js/infragistics.core.js"></script>
    <script src="https://secure-cdn-na.infragistics.com/igniteui/2017.1/latest/js/infragistics.dv.js"></script>
    <script src="https://secure-cdn-na.infragistics.com/igniteui/2017.1/latest/js/extensions/igniteui-angular.js"></script>

But I get the same error. It does load and appears to work but am concerned about the error. This is happening in IE 11.
