Getting an error of Exception: TypeError: stream.listeners is not a function from Serverless node-module

[Vikas252]

I am currently using serverless-http for azure with express while going through the state i got an error from serverless node module. I have integrate it with serverless framework.

Here is the error i'm getting:

And this is my server setup and serverless-http setup hello.js:

"use strict"

const serverless = require("serverless-http")
const express = require("express")

const app = express()
const router = express.Router()
app.set("port", process.env.PORT || 3000 )
app.listen(app.get("port"), () => {
  console.log(`listening on port ${app.get("port")}`)
})

router.get("/api/serverless", (req, res) => {
  res.json("Hi")
})

app.use("/", router)

const handler = serverless(app, { provider: 'azure' });
module.exports.handlertest = async (context, req) => {
  context.res = await handler(context, req);
}

// Export your express server so you can import it in the lambda function.
module.exports = app

// app.use(/* register your middleware as normal */)

serverless.yml:

# Welcome to Serverless!
#
# This file is the main config file for your service.
# It's very minimal at this point and uses default values.
# You can always add more config options for more control.
# We've included some commented out config examples here.
# Just uncomment any of them to get that config option.
#
# For full config options, check the docs:
#    docs.serverless.com

# Happy Coding!
