in Ember, Can I (de)serialize 3 level Nested JSON with DS.EmbeddedRecordsMixin?

My server returns JSON like below and I cannot change it into sideloading style.

{
  "owner": {
    "id": 293,
    "servers": [{
      "id": 32,
      "hostname": "host1",
      "networks": [ {
        "id": 1234,
        "ip": 10.10.10.10
      }, {
        "id": 5678,
        "ip": 10.10.20.10
      }]
    }, {
      "id": 33,
      "hostname": "host2",
      "networks": [ {
        "id": 1234,
        "ip": 10.10.10.11
      }, {
        "id": 5678,
        "ip": 10.10.20.11
      }]
    }]
  }
}

There is one and only API endpoint for serving above single JSON, and for it, I written three models - owner, server, network - setup like below:

network:

import DS from 'ember-data';
export default DS.Model.extend({
  servers: DS.hasMany('server'),
});

server:

import DS from 'ember-data';
export default DS.Model.extend({
  hostname: DS.attr('string'),
  owner: DS.belongsTo('owner', {async: true}),
  networks: DS.hasMany('network', {async: true}),
});

owner:

import DS from 'ember-data';
export default DS.Model.extend({
  servers: DS.hasMany('server', {async: true}),
});

Serializer for owner and server like this:

import TestSerializer from './test';
import DS from 'ember-data';
export default TestSerializer.extend(DS.EmbeddedRecordsMixin, {
  attrs: {
    servers: { embedded: 'always' },
  }
});

import TestSerializer from './test';
import DS from 'ember-data';
export default TestSerializer.extend(DS.EmbeddedRecordsMixin, {
  attrs: {
    networks: { embedded: 'always' },
  } 
});

when I run it without network-server relation, server-owner relation solved by serializer and it is find. but with 3 level relation, it fails with very long error:

So, Can I use EmbeddedRecordsMixin for it? or how can I get right result on this condition?
