ArrayUtil undefined, maybe missing global qualifier

[Thomas20]

New to ServiceNow development. Trying to create a widget that counts the number of non-duplicate entries in a table. I wrote some code in the widget's Server Script.

Code (taken from https://docs.servicenow.com/bundle/newyork-application-development/page/app-store/dev_portal/API_ref...😞

    var arrayUtil = new ArrayUtil();
    var a1 = new Array("a", "b", "c", "c", "b");
    gs.print(arrayUtil.unique(a1));

Error Message: ArrayUtil undefined, maybe missing global qualifier

Not sure what I'm doing wrong. Am I putting the script in the right spot?

Are you calling the ArrayUtil from scoped application? Then update below line as

var arrayUtil = new global.ArrayUtil();

Hi Thomas,

It would be great if you comeback and mark my response ACCEPTED & HELPFUL if your question has been answered. So that this can be displayed at the top of the list and others with same question can be benefited by this.

Thanks & Regards,

Adding a nice article on ArrayUtils usage in global vs scoped application and its method with example scripts. Hopefully, this will help future readers.
