I am calling /tasks//subtasks with the following data

```
{"data": {
"approval_status":"pending",
"assignee":"<AssigneeID>",
"completed":false,
"completed_by":null,
"custom_fields":null,
"due_at":null,
"due_on":null,
"external":null,
"followers":null,
"html_notes":null,
"liked":false,
"name":"Examine original report",
"notes":"",
"parent":"<parentID>",
"projects":null,
"resource_subtype":"default_task",
"start_on":null,
"tags":null,
"workspace":"<workspaceID>"
}

```

It is successfully creating a subtask but it is empty of any of the data I am passing

Hi @asher.brooks,

A few potential issues I can see:

1. The account you’re attempting to write to - is it at the Business or Enterprise level? `approval_status` is only available at those levels, otherwise the task creation won’t be successful.
2. Don’t specify `parent`. You’re providing the parent’s gid in the URL string itself (that’s been left out in your example but I assume that happened here in the forum when you tried to paste something in there).
3. `completed_by` is not writeable; leave that out.
4. In fact, just omit any field that’s `null`; there’s no value in sending those.

Thanks for replay Phil,

The account definetly has the right permissions becuase the post is successful.

Hmm, I don’t know why it’s not working properly.

Have you tried creating a top-level task (not a subtask) and does it do the same thing?

Have you tried creating it in Postman (or equivalent tool) - if not, I would recommend doing that, to see if it’s somehow a function of your specific client environment (though I can’t imagine what that would be that would create the task but not populate the name).

Has a solution been found for this? My Fetch will only create blank tasks too

@Brian_Lynch can you share the request you are making? I never had an issue with this 😕
