Question

嗨，我正在使用Java高级rest api客户端从弹性搜索索引中读取一些文档，并且出现以下错误。

当我确实对Elasticsearch客户端执行如下请求时，出现此错误。

elasticSearchClient.search（searchRequest，RequestOptions.DEFAULT）;

java.lang.IllegalArgumentException: cannot write xcontent for unknown value of type class java.util.UUID
    at org.elasticsearch.common.xcontent.XContentBuilder.unknownValue(XContentBuilder.java:833)

以下是我的弹性搜索索引的内容。

任何想法导致此错误的原因是什么。我正在使用弹性搜索Java Rest Client API版本6.6.1

非常感谢您的帮助谢谢

我已经使用toString（）解决了此问题，messageHistoryFilterRequest.getAccountId（）返回的是java.util.UUID。弹性搜索不了解UUID。所以一旦我做一个toString（）它就解决了

if (messageHistoryFilterRequest.getAccountId() != null) {
    MatchQueryBuilder matchQueryBuilder = new MatchQueryBuilder("account_id",
            messageHistoryFilterRequest.getAccountId().toString());
    boolQueryBuilder.must(matchQueryBuilder);
}

if (messageHistoryFilterRequest.getCampaignId() != null) {
    MatchQueryBuilder matchQueryBuilder = new MatchQueryBuilder("campaign_id",
            messageHistoryFilterRequest.getCampaignId().toString());
    boolQueryBuilder.must(matchQueryBuilder);
}

if (messageHistoryFilterRequest.getFlightId() != null) {
    MatchQueryBuilder matchQueryBuilder = new MatchQueryBuilder("flight_id",
            messageHistoryFilterRequest.getFlightId().toString());
    boolQueryBuilder.must(matchQueryBuilder);
}

java.lang.IllegalArgumentException：无法为类型为java.util.UUID类型的未知值编写xcontent？
