Ruby on rails 在AMI上建立太阳黑子Solr

我正在尝试在运行AMI的EC2实例上设置我的应用程序（Ror4.0，Sunspot）的开发版本。我有

gem安装sunspot\u solr

然后

bundle exec rake sunspot:solr:start

看来太阳黑子开始正常了。我还可以通过web界面访问它。然后问题出现了，每当我尝试添加新对象时，都会出现500个内部服务器错误：

从web界面上看，它似乎与Dataimport处理程序有关？当我点击我的核心的DIH时，它显示：

我只是按照《太阳黑子站点快速入门指南》进行操作，在本地机器上运行良好。我在EC2上设置它的方式完全相同，但就是不起作用。因此，我认为它与DIH无关（因为我还没有在本地机器上定义DIH配置）

我已经寻找了两天的解决方案，但没有运气。。。。任何想法都将不胜感激

多谢各位
