Estoy implementando el módulo de clúster de nodeJS en serverless. el clúster no pudo escuchar el puerto sin servidor, por lo que después de ejecutar sin servidor obtengo el siguiente problema

 offline: Failure: offline: handler 'handler' in /home/Documents/cluster is not a function Error: offline: handler 'handler' in /home/Documents/cluster is not a function at InProcessRunner.run (/home/Documents/node_modules/serverless-offline/dist/lambda/handler-runner/in-process-runner/InProcessRunner.js:160:13) at processTicksAndRejections (node:internal/process/task_queues:96:5) at async LambdaFunction.runHandler (/home/Documents/node_modules/serverless-offline/dist/lambda/LambdaFunction.js:368:20) at async hapiHandler (/home/Documents/node_modules/serverless-offline/dist/events/http/HttpServer.js:702:18) at async exports.Manager.execute (/home/Documents/node_modules/@hapi/hapi/lib/toolkit.js:60:28) at async Object.internals.handler (/home/Documents/node_modules/@hapi/hapi/lib/handler.js:46:20) at async exports.execute (/home/Documents/node_modules/@hapi/hapi/lib/handler.js:31:20) at async Request._lifecycle (/home/Documents/node_modules/@hapi/hapi/lib/request.js:371:32) at async Request._execute (/home/Documents/node_modules/@hapi/hapi/lib/request.js:281:9)

siguiente es mi grupo

clúster.js

 const cluster = require("cluster"); const totalCPUs = require("os").cpus().length; const serverless = require("serverless-http"); const app = require("./api"); console.log("cluster.isMaster", cluster.isMaster); if (cluster.isMaster) { console.log(`Number of CPUs is ${totalCPUs}`); console.log(`Master ${process.pid} is running`); // Fork workers. for (let i = 0; i < totalCPUs; i++) { cluster.fork(); } cluster.on("exit", (worker, code, signal) => { // console.log(`process killed:`, worker.kill()); console.log(`${worker.process.pid} is killed`); // console.log("code, signal ", code, signal); cluster.fork(); // console.log(`new proccess pid: ${process.pid}`); }); } else { module.exports.handler = serverless(app); }

aplicación.js

 const express = require("express"); const app = express(); // require("dotenv").config() const cluster = require("cluster"); const totalCPUs = require("os").cpus().length; app.get("/", (req, res) => { console.log(`Hello World! - on process ${process.pid}`); res.send("Hello World!"); // process.exit(0); }); module.export = app

después de todo esto, automáticamente mata todo el proceso.

 - 15947 is killed - 15961 is killed - 15968 is killed - 15954 is killed
