scala - Elasticsearch脚本将元素添加到数组中

Question

我正在一个scala项目中从事ElasticSearch的工作。我正在使用elastic4s作为客户端。我试图将元素从一个迭代器一个接一个地添加到文档中。

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
}

上面的代码不起作用，产生以下错误:

问题出在我假定的脚本上，但找不到任何解决方案。请帮忙...

添加groovy依赖性是否可以解决问题？请注意:gist。
