ElasticSearch TypeError：请求路径包含未转义的字符

Question

我正在编写服务器代码，用于侦听firebase数据库上的搜索请求并返回搜索结果。这是将Firebase数据库中的数据编入索引到Elastic Search的代码。这是索引数据的正确方法吗？

var firebase = require('firebase');
var ElasticClient = require('elasticsearchclient');

// listen for changes to Firebase data
var client = new ElasticClient({host:'localhost',port:9200});

firebase.initializeApp({
    serviceAccount: {
        ...
    },

    databaseURL: "https://searchserver.firebaseio.com/"
})

var db = firebase.database();
var ref = db.ref("realtime");

ref.on('child_added', upsert);
ref.on('child_changed', upsert);
ref.on('child_removed', remove);

function upsert(snap) {
    client.index({
        index: 'firebase',
        type: 'users',
        id: snap.key,
        body: snap.val()
    }, function (err, response) {
        if (err) {
            console.log("error indexing " + error)
        }
    });
}

function remove(snap) {
    client.delete({
        index: 'firebase',
        type: 'users',
        id: snap.key
    }, function (error, response) {
        if (error) {
            console.log("Error deleting user : " + error);
        }
    });
}

这是错误消息。
