Scala Elasticsearch脚本将元素添加到数组中

我在scala项目中从事ElasticSearch。我使用elastic4s作为客户。我试图从迭代器一个接一个地向文档中添加元素

while (iterator.hasNext) {
  counter +=1
  client.execute {
    update id reportID in "reports/report" script "ctx._source.elasticData += output" params Map("output" -> iterator.next().toStringifiedJson)
  }.await
}

上述代码不起作用，产生以下错误：

问题在于我假设的脚本，但我找不到任何解决方案。请帮助…

添加groovy依赖项可以解决问题吗？请看：。

添加groovy依赖项是否解决了问题？请看这里：不，我已经尝试过@OpalDoes此帮助（如果使用1.4之前的ES），您使用的ES版本是什么。从1.3.x到1.4.x的情况有所改变，您需要做的是改变以支持脚本和可能的groovy，但根据您的版本有所不同@Opal的第一个链接这次确实起了作用，谢谢大家。要清楚的是，不是elastic4s需要dep，而是任何基于Java的ES客户端，e4s就是其中之一。
