我正在尝试在运行AMI的EC2实例上设置我的应用程序的开发版本（RoR 4.0，Sunspot）。我有gem install sunspot_solr然后bundle exec rake sunspot:solr:start
太阳黑子似乎正常开始。我也可以通过网络界面访问它。然后出现问题，每当我尝试添加新对象时，就会出现500内部服务器错误：

然后我尝试重新索引太阳黑子以进行故障排除。它返回一个类似的错误：
Error - RSolr::Error::Http - 500 Internal Server Error - retrying...
Error - RSolr::Error::Http - 500 Internal Server Error - ignoring...
Error - RSolr::Error::Http - 500 Internal Server Error - retrying...

从网络界面看，它似乎与Dataimport Handler相关？当我点击我的核心DIH时，它显示：

我刚刚关注太阳黑子网站上的快速入门指南，它在本地计算机上工作得很好。我设置它的方式与EC2完全相同，但它不起作用。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）。
我一直在寻找解决方案两天但没有运气......任何想法都会非常感激！
谢谢
