Tengo una aplicación Express/Node.js simple con los siguientes archivos sin subdirectorios (aparte de .serverless y node_modules).

• .sin servidor
• node_modules
• aplicación.js
• lambda.js
• paquete.json
• paquete-bloqueo.json
• sin servidor.yml

AWS arroja este error: se produjo un error: ApiLambdaFunction: el archivo cargado debe ser un zip no vacío (Servicio: AWSLambdaInternal; Código de estado: 400; Código de error: InvalidParameterValueException; ID de solicitud: 5779d4c3-beaa-4bc2-b525-c1e89a82635a; Proxy: nulo).

El archivo .zip no estaba vacío cuando accedí al depósito S3 al que se carga el código. Pude ver la carpeta .zip con todo su contenido allí. Sin embargo, la operación de serverless deploy falla desde AWS CLI, lo que genera la excepción anterior. Cualquier ayuda para concentrarse en el problema sería muy apreciada. ¡Gracias!

A continuación se muestra el código.

• aplicación.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", (req, 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) }

• paquete.json
