The name of a JavaScript function used to handle the PreviewClick event.


Each time an error occurs on the server, the OnServerError event is raised on the client side. Handle this event to perform actions when a Fetch request completes with an error.

window.ReportingDesignerCustomization = {
    onError: function(s, e) {
      alert("An internal server error has occurred.");
