使用Firebase进行弹性搜索没有响应？

Question

我没有从弹性搜索中得到任何响应，它只是返回了这个值，我猜测弹性搜索没有要搜索的数据，可能是因为Firebase和弹性搜索模型在某处有所不同，我不知道任何人都可以帮忙我

const functions = require('firebase-functions');

const request = require('request-promise')

exports.indexPostsToElastic = functions.database.ref('/hostels/{hostel_Id}')
.onWrite(event => {
    let postData = event.data.val();
    let hostel_Id= event.params.hostel_Id;

    console.log('Indexing post:', postData);

    let elasticSearchConfig = functions.config().elasticsearch;
    let elasticSearchUrl = elasticSearchConfig.url + 'hostels/' + hostel_Id;
    let elasticSearchMethod = postData ? 'POST' : 'DELETE';

    let elasticSearchRequest = {
        method: elasticSearchMethod,
        url: elasticSearchUrl,
        auth:{
            username: elasticSearchConfig.username,
            password: elasticSearchConfig.password,
        },
        body: postData,
        json: true

      return request(elasticSearchRequest).then(response => {
         console.log("ElasticSearch response", response);
