Need help on UI Page

[AbhitK]

Hi All,
I need some help here.
Use Case- Restrict attachment insertion for more than 25 MB on knowledge table but this restriction should not be applied for view HR(custom view). Also the warning which is added on attachment UI Page should not be visible to knowledge record where view is HR.
The solution which I have right now works well post submission of record but doesn't work on new record.
Here are the snapshot:
Business Rule (On attachment table, before business rule)

2. UI Page:

On UI page I'm trying get the view of new knowledge record, but it is giving me log in null.
Any help on this would be a great help.

            var checkAttachmentSize;
            var attachmentFlag = false;

            var kbRecord = new global.Hnk_project_process().getKnowledgeBase(current.table_sys_id);
            // If the base table matches and the attachment exceeds max size, restrict it
            if ((allowedTables.includes(baseTable) && !grRecord.startsWith('Human')) || (attachemtTable == 'kb_knowledge' && !kbRecord.startsWith('HR'))) {
                checkAttachmentSize = new global.Hnk_project_process().getAttachmentSize(current);
                var totalSize = parseInt(current.size_bytes) + checkAttachmentSize;
                var maxSize = 25 * 1024 * 1024;
                if (totalSize > maxSize) {
                    attachmentFlag = true;
                    gs.addErrorMessage('Total attachments on this record cannot exceed 25 MB.');
                    current.setAbortAction(true);

@AbhitK 

if you are planning to customize the OOTB attachment UI page, I will recommend not to do that.

I will push back on this requirement as you are touching an OOTB component.

@Ankur Bawiskar  it's already customized and this is how we are restricting heading 
 <j2:if test="$[!scope.contains('sn_hr')]"> 

    <j2:if test="$[!scope]">

        <!--<j2:if test="$[jvar_sysparm_view.indexOf('askhr') != 0]">-->

        <h3 style="text-align: center; font-size: 15px; font-weight: bold;">Restrict the file upload of size more than 25MB.</h3>

    </j2:if>

    <input type="hidden" id="ni.show_rename_link" name="ni.show_rename_link" value="${jvar_can_add_attachments}" />
