I've been trying for some time to make a "Dial chart component" in my dashboard. When I hit preview, it shows the loading icon and then shows a blank page. It doesn't render the dial chart.

When I took the "Chartbeans Dial Chart" example from the "Chart examples" folder, I'm getting the following error:

The Pentaho BI Platform reported an error while running an action sequence
Possible Causes:
