Below script, working fine [Response]

(function process( /*RESTAPIRequest*/ request, /*RESTAPIResponse*/ response) {
    var getID = request.pathParams.sysid;
    var grt = request.body.data;
    var gr = new GlideRecord('incident');
    gr.addQuery('sys_id', getID);
    gr.query();
    if (gr.next()) {
        gr.short_description = grt.short_description;
        gr.contact_type = grt.contact_type;
        gr.update();
		return getID;       //perfectly returning sysid
    }
})(request, response);

    gr.addQuery('sys_id', getID);
    gr.query();
    if (gr.next()) {
        gr.short_description = grt.short_description;
        gr.contact_type = grt.contact_type;
        gr.update();
    }

I could see you have marked few of my blogs and comments as helpful.

Please read them and if they helped then only mark them helpful.

I would suggest not to blindly mark those as helpful.

Please avoid this practice as it is not good.
