> }).catch((err) => {
> console.log(err);
> });
> 
> ```

Output

Can you share what the server response actually looks like? This seems like you’re handing something to ember-data that isn’t a valid response.

ya , it’s my mistake , because findAll need array but i have object , that’s why i got error , but you have any idea how to get object, like this

> ```
> {
> count: 3,
> message: 'Successfully get',
> data: [
> {},{},{}
> ]
> }
> 
> ```

That depends on what server you’re using. You can change your server to match [https://jsonapi.org/](https://jsonapi.org/), or you can write a [custom serializer](https://guides.emberjs.com/release/models/customizing-serializers/) to make ember-data understand whatever format your server is using.
