    var taskGroup_Items = Tasks.Tasks.list(taskGroup.items[i].id)

In your script, how about the following modification?

From:

Tasks.Tasks.get(taskGroup_Items.items[j].parent).title

To:

taskGroup_Items.items[j].parent ? Tasks.Tasks.get(taskGroup.items[i].id, taskGroup_Items.items[j].parent).title : ""

• In this case, Tasks.Tasks.get(taskGroup.items[i].id, taskGroup_Items.items[j].parent).title can be also used. But, even when taskGroup_Items.items[j].parent is undefined, no value from Tasks.Tasks.get is returned. By this, the process cost becomes hign. So, I proposed this modification.

Reference:

• Method: tasks.get
