        var ga = new GlideAjax('uiBuilderAction');

        ga.addParam('sysparm_name', 'cancelIncidentIncident');

        ga.addParam('sysparm_id', g_form.getUniqueValue());

        ga.getXMLAnswer(function(response) {

            if (response) {

                var result = response;

                if (result != 'success') {

                    g_form.addErrorMessage('Error: ' + result);

                } else {

                    g_form.save();

                }

            } else {

You cannot use GlideAjax and script includes in workspace. 

For your use case I would consider creating a Data Broker Server Script (sys_ux_data_broker_transform). Here you can do server-side actions based on inputs from your page and return an output based on the script evaluation. Just ensure to check "Mutates server data" to be able to execute the Data resource with an event.

This video briefly describes the concept: https://www.youtube.com/watch?v=QrTc8PTOHmc

I tried, but it doesn't work now. I have tried this lesson.

Although I still haven't been able to initiate a request in SOW, at least I know that this problem is not facing me alone. Doesn't ServiceNow official know about the existence of this problem and provide a simple and feasible solution?
