GlideSysAttachment().copy Not copying the attachment - HR Scoped application

[Mrman]

Hi Team,

I have created a after insert BR to insert a HR task and then copy a specific attachment from a Case to HR task .

The attachment is not getting copied to HR task. Please suggest 

All the log messages are getting triggered correctly , but the attachment is not found on target record.

(function executeRule(current, previous /*null when async*/ ) {

    gs.info("the BR triggerred for status");

    var grCattch = new GlideRecord('sys_attachment');
    grCattch.addQuery('table_name', 'sn_hr_core_case_workforce_admin');
    grCattch.addQuery('table_sys_id', current.sys_id);
	grCattch.addEncodedQuery('file_nameSTARTSWITHStatus Record Certificate');
    grCattch.query();

    if (grCattch.next()) {
		

        var grCmnl = new GlideRecord('sn_hr_core_task');
        grCmnl.initialize();
        grCmnl.parent = current.sys_id;
        grCmnl.assignment_group = '3506330cdbc92054e803f3551d9619b0';
        grCmnl.state = '10';
        grCmnl.short_description = "Validate Status Record";
        grCmnl.insert();
		

gs.info("the record status is found " + 'attchsysid----' + grCattch.getUniqueValue() + 'attchtable---' + grCattch.getTableName() + 'tasktable----' + grCmnl.getTableName() + 'tasksysid---' + grCmnl.getUniqueValue());

		new GlideSysAttachment().copy(grCattch.getTableName(), grCattch.getUniqueValue(), grCmnl.getTableName(), grCmnl.getUniqueValue());
    }

@Ankur Bawiskar Please let me if the previous code using writeContentStream will work in Scoped application , so that I can try.

[Ankur Bawiskar]

Try that once
