Temporary fix is to add a service reference to your own Config class in app/config/services.yml before installing the package:

services:
  json_api.config:
    class: REST\CommonBundle\JsonApiConfig

This class must extend Elytus\LimoncelloBundle\Config\ConfigInterface and follow the example found in ExampleConfig.php
