Custom Macro to generate Audit Tables is not working

Toad Data Modeler
1

I Created a Custom Macro on Toad Data Modeler, Version 8.0
This macro is suppose to generate Audit tables for all the entities I have in the Model, when I run the macro it does nothing. Any help on this will be greatly appreciated.

Here is my Macro

function main() {
    var App = System.GetInterface("Application");
    var Model = App.ActiveModel;
    var WS = App.ActiveWorkSpace;
    var Log = System.CreateObject("Log");
    Log.Information("Audit tables created for all tables.");
    if (Model == null)
        return;
    for (var i = 0; i < Model.Tables.Count; i++) {
        var origTable = Model.Tables.GetObject(i);
        var auditTableName = origTable.Name + "_AUDIT";
        // Skip if audit table already exists
        if (Model.Tables.GetObjectByName(auditTableName)) continue;

        var auditTable = Model.Tables.CreateNew();
        auditTable.Name = auditTableName;
        auditTable.Caption = origTable.Caption + " Audit";

        // Copy columns from original table
        for (var j = 0; j < origTable.Columns.Count; j++) {
            var col = origTable.Columns.GetObject(j);
            var newCol = auditTable.CreateColumn();
            newCol.Name = col.Name;
            newCol.DataType = col.DataType;
            newCol.Length = col.Length;
            newCol.Precision = col.Precision;
            newCol.Scale = col.Scale;
            newCol.Mandatory = false; // Set to nullable for audit
        }

        // Add audit columns
        var auditId = auditTable.CreateColumn();
        auditId.Name = "audit_id";
        auditId.DataType = "NUMBER";
        auditId.Mandatory = true;
        
        var auditDts = auditTable.CreateColumn();
        auditDts.Name = "audit_dts";
        auditDts.DataType = "TIMESTAMP";
        auditDts.Mandatory = true;        
        
        var auditOp = auditTable.CreateColumn();
        auditOp.Name = "audit_op";
        auditOp.DataType = "CHAR";
        auditOp.Length = 20;
        auditOp.Mandatory = true;

        var auditUser = auditTable.CreateColumn();
        auditUser.Name = "audit_user";
        auditUser.DataType = "VARCHAR2";
        auditUser.Length = 20;
        auditUser.Mandatory = true;

        // Add the new audit table to the model
        Model.Tables.Add(auditTable);
    }
}
