Show attachment of parent case on portal

[Rosy14]

Hi,

I want to show all the attachment of parent case on portal

Below code is not working

Script include:

var att = new GlideRecord("sys_attachment");

                        att.addQuery("table_sys_id", taskGR.parent);

                        att.query();

                        while (att.next()) {

                            data.attachment = gs.getMessage(att);

                        }

HTML:

Attachment: {{data.attachment}}

The requirement is to bring all attachment of parent case to child task.
