上传的文件必须是非空的 zip服务：AWSLambdaInternal；状态代码：400；错误代码：InvalidParameterValueException；

问题描述

我有一个简单的 Express/Node.js 应用程序，其中包含以下没有子目录的文件（除了 .serverless 和 node_modules）。

.无服务器
node_modules
app.js
lambda.js
package.json
package-lock.json
无服务器.yml

AWS 抛出此错误 - 发生错误：ApiLambdaFunction - 上传的文件必须是非空 zip（服务：AWSLambdaInternal；状态代码：400；错误代码：InvalidParameterValueException；请求 ID：5779d4c3-beaa-4bc2- b525-c1e89a82635a；代理：null）。

当我访问代码上传到的 S3 存储桶时，.zip 文件不是空的。我能够看到 .zip 文件夹及其所有内容，但是，serverless deploy 操作从 AWS CLI 失败，引发上述异常。任何帮助将问题归零将不胜感激。谢谢！

以下是代码。

app.js

const express = require("express")
const app = express();

app.use(express.json());
app.use(express.urlencoded({extended: false}));

app.get("/",(req,res) => {
    res.status(200).send("Root endpoint")
})

app.post("/postReq",res) => {
    res.status(200).send(req.body);
})

app.listen(8080,() => console.log("App started."))

lambda.js

'use strict'
const awsServerlessExpress = require('aws-serverless-express')
const app = require('./app')
const server = awsServerlessExpress.createServer(app)

exports.handler = (event,context) => { awsServerlessExpress.proxy(server,event,context) }

package.json

解决方法

此问题是由当前在节点版本 15.6.0 或更高版本上运行时 serverless 内部使用的 archiverjs/node-archiver 依赖项引起的。

正如 MX D 在他的 here 中提到的那样，许多提议的 comment 将节点版本降级到当前的 LTS 版本 v14.15.4 或 v15.5.1 应该可以正常工作。

许多人在 CI/CD 管道中构建他们的包时遇到这个问题，因为他们使用的是节点 docker 镜像。例如在 GitLab 中，如：

default:
    image: node:alpine

除了 node:alpine，错误也应该发生在 node:latest 等上。这些行应该更改为上述特定的工作版本，如下所示：

default:
    image: node:15.5.1
