I have created a server-side javascript activity as follows. I also have a automation created via automation studio which executes the server-side script. It is succeeding each time however I don't see the update being done on the data extension. How can I debug to see the error msg?
<script runat="server">
Platform.Load("core","1");
try {
var caslDE = DataExtension.Init("6C119FFD-0EF5-476A-8127-E2E70D80ED04");
caslDE.Rows.Update({Source:"EXACT"}, ["Prospect Type"], ["A"]);
} catch (ex) {
Write("An error has occurred: " + Stringify(ex));
}
</script>
