    In your code, try changing “this.DEPT” to “__parent__.DEPT”. I think “this” is scoped to the new object you’re creating, so you need to reference the object parent.

    {
    "DEPT": {
        "EG": "Engineering",
        "HR": "Human Resource",
        "FIN": "FInance"
    },
    "AddDescription": element => (element.filter(x=>x.sector=='USA').map(x=> x.extend({"Description":__parent__.DEPT.get(x.deptId)})).filter(x=>x.get('Description')!=null))
}
