Possible Unhandled Promise Rejection

[complexcode-de]

I'm calling the the fetch method in

async componentWillMount() {
        connectAPI(await AsyncStorage.getItem('userToken'));
        // this._fetchMore();
        await ProductCollection.fetch();
    }

I got following error when I'm fetching the collection.

Possible Unhandled Promise Rejection (id: 0):
ErrorObject {
  "error": null,
  "payload": Object {},
  "requestResponse": null,
}

What I'm doing wrong?

What is the API returning? fetch will fail if the request fails.
