Getting error org.mozilla.javascript.NativeArray

[Community Alums]

I have a requirement where I want to fetch all the computer names from cmdb_ci_computer table that are assigned to requester and also want to set the field with newly assigned computer.

there is existing script include as well as catalog client script  but when I used array it throws the error org.mozilla.javascript.NativeArray 

Please suggest ,what is going wrong here 

Catalog client script:- 

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }

    var ga = new GlideAjax('PL4UserServiceAjax');
    ga.addParam('sysparm_name', 'getUserComputer');
    ga.addParam('sysparm_user', newValue);
    ga.getXMLAnswer(setComputer);
}

function setComputer(response){
    g_form.setValue('Computername', response);

}

Script include :- 

getUserComputer: function(userId) {
        var host =[];
        var comp = new GlideRecord("cmdb_ci_computer");
        comp.addQuery("assigned_to", userId);
    //    comp.orderByDesc("sys_created_on");
        comp.query();
        while (comp.next()) {
            var str = (comp.getValue("name"));
            host.push(str);
        }     
        return host;
    },

Reference Qualifier:-assigned_to=gs.getUserID()^install_status!=7^sys_class_name=cmdb_ci_computer^EQ

Default Value:- javascript: new PL4UserService().getUserComputer(gs.getUserID())
