After creating a record with this.datastore.createRecord(Example, {}) and using save().subscribe((example: Example) => { console.log(example); }), it is not possible to catch an error if the HTTP response has an error status code (e.g. "400 Bad Request") because saveRecord returns an Observable of the model.

It would be better to use the default handleError method of JsonApiDatastore if an error occurs when saving a record.
