Does the “mark as done” operation send a PUT/PATCH request correclty? And assuming the answer is yes, what is the response payload from the server?

ok, i tried again and again but unable to solve 😄
Here is the response payload - After Clicking “Mark as Done”
```auto
{
"title": "No Title",
"priyority": "NORMAL",
"createdAt": "2022-09-29T03:32:17.000Z",
"isCompleted": true,
"isDeleted": false
}
```

Ah ok so Ember Data expects that response to have the full record data (including the id) but the server isn’t providing the `id` in the response, so Ember Data is throwing that error because essentially it’s going to overwrite the id that is there to `null`. Ideally your server should send the `id` in this payload.

Hmmm those stack traces aren’t super revealing 🤔
What does the `DELETE` request/response look like? It’s possible it’s a similar thing where Ember Data expects one thing and your server does something different so the server deletes the record but the client chokes on the reponse.

DELETE Response From Server is -
and my delete operation in controller is -
> app/controllers/index.js
```auto
@action
deleteTask(taskId) {
let task = this.store.peekRecord('tasks', taskId);
task.deleteRecord();
task.save();
}
```

ok… i’m not 100% sure if this is the issue but i think Ember Data expects either:
- a 200 response with an empty object in the body `{ }`
- OR at 204 response with no body
Giving it a 200 with a string payload might be confusing it, so that would be my first guess is to try one of the above instead.
