Elasticsearch 5-奇怪的错误（值源配置无效；必须具有字段上下文或脚本或标记为未包装）

Question

我正忙于将Java平台从ES 2升级到ES 5.4.3，到目前为止一切正常，除了一个查询返回的错误不是必须的。有人看过吗？

Answer 1

我不确定没有更多的上下文，但是我会在这里指出，我通过向我之前缺少的AggregationBuilders中添加“ field”属性来解决了该错误。

之前：

RangeAggregationBuilder range = AggregationBuilders.range("range_name");

之后：

RangeAggregationBuilder range = AggregationBuilders.range("range_name").field("whatever.mapping.you.need");

同样，在没有进一步背景的情况下，在您的具体情况下真的很难说。但是考虑到这是Java（这是我的问题），而不是与kibana相关，并且由于我的解决方案如此简单，我希望遇到此问题的某个人（可能是future-me）能看到这一点，并为此省去很多麻烦。] >
