Cannot set properties of undefined (setting 'ko')

Question

When calling like that i recive an error

var chart = anychart.sunburst(data, "as-tree");
chart.tooltip().useHtml(true);
chart.container("mdl_4000_01_a3_chart");
chart.fullScreen(true)

It works without fullScreen but graph is very small sized

Uncaught TypeError: Cannot set properties of undefined (setting 'ko') anychart-core.min.js:809
