I have setup a project in Asana that will be used as a template for many new projects that will be created using the API. They all need to have the same tasks and subtasks. However, when I use the API endpoint /duplicate, it is only duplicating the tasks, not the subtasks. Is this working as intended? Duplicating through the UI duplicates both, so this seems inconsistent. Any help would be great. Thanks! ---

Actually found the answer in another question. I had tried to include subtask, but finally got an error message explaining it: ``` "include": ["task_subtasks"], ``` Include options: {forms, members, notes, task\_assignee, task\_attachments, task\_dates, task\_dependencies, task\_followers, task\_notes, task\_projects, task\_subtasks, task\_tags} ---
