NodeJS Async-Await函数在被调用时导致服务器崩溃

我正在尝试构建一个节点应用程序，使用Nodemon作为应用程序的实时服务器。这是一个简单的新闻通讯注册Web应用程序，使用Mailchimp API来存储已注册人员的列表。
在我的app.js中，我使用了Mailchimp开发人员指南中的模板代码的编辑版本，我发现我使用的async/await函数在将数据发布到Mailchimp服务器时存在问题。
下面是Mailchimp开发人员指南中的文章链接：text
下面是我在app.js中的代码：

//Requiring mailchimp's module
//For this we need to install the npm module @mailchimp/mailchimp_marketing. To do that we write:
//npm install @mailchimp/mailchimp_marketing
const mailchimp = require("@mailchimp/mailchimp_marketing");
//Requiring express and body parser and initializing the constant "app"
const express = require("express");
const bodyParser = require("body-parser");
const app = express();
//Using body-parser
app.use(bodyParser.urlencoded({extended:true}));
//The public folder which holds the CSS
app.use(express.static("public"));
//Listening on port 3000 and if it goes well then logging a message saying that the server is running
app.listen(process.env.PORT||3000,function () {
 console.log("Server is running at port 3000");
});
//Sending the signup.html file to the browser as soon as a request is made on localhost:3000
app.get("/", function (req, res) {
 res.sendFile(__dirname + "/signup.html");
});
//Setting up MailChimp
mailchimp.setConfig({
//*****************************ENTER YOUR API KEY HERE******************************
 apiKey: "7825a331ceaec9fa7c606108d9eee46d-us21",
//*****************************ENTER YOUR API KEY PREFIX HERE i.e.THE SERVER******************************
 server: "us21"
});
//As soon as the sign in button is pressed execute this
app.post("/", function (req,res) {
//*****************************CHANGE THIS ACCORDING TO THE VALUES YOU HAVE ENTERED IN THE INPUT ATTRIBUTE IN HTML******************************
const firstName = req.body.fName;
const lastName = req.body.lName;
const email = req.body.email;
//*****************************ENTER YOU LIST ID HERE******************************
const listId = "2fdb4c478c";
//Creating an object with the users data
const subscribingUser = {
 firstName: firstName,
 lastName: lastName,
 email: email
};
//Uploading the data to the server
 async function run() {
const response = await mailchimp.lists.addListMember(listId, {
 email_address: subscribingUser.email,
 status: "subscribed",
 merge_fields: {
 FNAME: subscribingUser.firstName,
 LNAME: subscribingUser.lastName
}
});

//If all goes well logging the contact's id
 res.sendFile(__dirname + "/success.html")
 console.log(
    `Successfully added contact as an audience member. The contact's id is ${
      response.id
    }.`
  );
}

//Running the function and catching the errors (if any)

// So the catch statement is executed when there is an error so if anything goes wrong the code in the catch code is executed. In the catch block we're sending back the failure page. This means if anything goes wrong send the faliure page
 run().catch(e => res.sendFile(__dirname + "/failure.html"));
});

我的signup.html页面，包含输入表单的结构（注意：它使用bootstrap中的模板，只有表单是重要的）：

我有两个页面的客户端被定向到输入他们的数据时，当运行正确，他们将被定向到一个成功的页面，他们的数据将被上传到Mailchimp服务器，但在启动现场服务器和点击注册按钮与上述代码，我被重定向到失败的页面，并没有改变的终端，Nodemon已经开始（这是显示www.example.com）.response.id). When I try and call the async/await function run() directly below the code block:

console.log(
    `Successfully added contact as an audience member. The contact's id is ${
      response.id
    }.`

然后点击按钮，我再次被引导到失败页面，带有Nodemon的终端显示一长串代码错误，直到Nodemon服务器崩溃。代码块错误：

提供的API密钥和listID应该是有效的，但错误似乎指向了这一点。由于服务器在重新加载时崩溃，因此显示错误401。

根据documentation，401错误意味着“API密钥无效”。而且，错误还显示unauthorized: true和clientError: true，这更多地表明您的API密钥不正确。
所以，这个：

//Setting up MailChimp
mailchimp.setConfig({
 apiKey: "7825a331ceaec9fa7c606108d9eee46d-us21",
 server: "us21"
});

显然是不正确的。正如其他人所说，-us21可能不应该在apiKey上。或者您可能没有指定正确的server。在这两种情况下，这是需要修复以解决401错误的代码行。
你需要登录到你的mailchimp开发者帐户，并再次查看你的apiKey和服务器应该是什么。我们不能为你做这件事--这是你必须做的事情。
