Context.Done Azure函数Javascript多个异步调用

Question

我已经使用3次调用db创建了一个Azure函数。但是因为它们只是工作异步，所以只添加了第一项。 我的代码如下。所以准确地说Context.Done但首先，必须先完成调用才能进行下一次通话，希望有人可以帮助我。

它似乎与Azure功能上下文有关，因为承诺也不起作用。

const azure = require("azure-storage");
var feed = require('feed-read');
const env = require('dotenv').config();
const con = "storageconnection";
