Elasticsearch Javascript Client Update 不起作用

Question

我正在使用带有nodejs(Typescript(的elasticsearch JavaScript客户端。更新查询未按预期工作，任何人都可以帮助我解决这个问题

我的代码是

const EsResponse = await esClient.update({
index: "myindex",
type: "mytype",
id: "1",
body: {
// put the partial document under the `doc` key
doc: {
title: "Updated"
}
}
});

而回应是

{
"msg": "[invalid_type_name_exception] Document mapping type name can't start with '_', found: [_update]",
"path": "/myindex/_update/1",
"query": {
"type": "mytype"
},
"body": "{"doc":{"title":"Updated"}}",
"statusCode": 400,
"response": "{"error":{"root_cause":[{"type":"invalid_type_name_exception","reason":"Document mapping type name can't start with '_', found: [_update]"}],"type":"invalid_type_name_exception","reason":"Document mapping type name can't start with '_', found: [_update]"},"status":400}"
}

我的package.json文件是

{
"name": "backend",
"version": "1.0.0",
"description": "The backend system",
"main": "dist/index.js",
"scripts": {
"prebuild": "tslint -c tslint.json -p tsconfig.json --fix",

"prestart": "npm run build",

我的弹性搜索版本是 6.3

Answer 1

原因是您在 6.3 ES 集群上使用 7.x 客户端。

您只需使用apiVersion配置设置将客户端配置为与 6.x 群集通信，如下所示：

var elasticsearch = require('elasticsearch');
var client = new elasticsearch.Client({
... other config options ...
"apiVersion": "6.8"                 <--- add this line
});
