Issue with Duplicate Attachment Copying from HR Task to HR Case

[Satyam123]

I have created a business rule that uses the insert and update actions to copy attachments from an HR Task to an HR Case. However, I am still encountering issues with duplicate attachments being copied. Additionally, attachments are only being copied from the HR Task to the HR Case when I comment on the HR Task.

I want to add the attachment so that whenever I attach any document in the HR Task, it automatically sends it to the parent HR Case, only the newly added doc not all the previous one.
Thanks

(function executeRule(current, previous /*null when async*/) {
// Ensure attachments are only copied once
var hrCase = new GlideRecord('sn_hr_core_case');
if (hrCase.get(current.parent.sys_id) && !hrCase.attachments_copied) {

// Copy new attachments from HR Task to HR Case (you may have a specific function for this)
new hr_Task().updateAttachments(current);

// Set the flag to prevent re-copying
hrCase.attachments_copied = true;
hrCase.update();
}
})(current, previous);
