Serverless-offline httpApi / post not working / but works on deployed version deployed


I’m having a very basic (hello-world-style) application where I have a GET/POST on a specific path (see code bellow).
The GET seems to work as expected / the POST is never reaching my code (I think).
I use postman to check the results of the lambda function.
If I deploy the lambda - and execute the same postman-requests on the deployed version - it does work.

I wrote a log message when my code gets called - If I do the test through sls offline - this log message only appears after I do a GET request.
If I start offline (sls offline) and do a POST request in postman - this log-message never appears.

 Operating System:          win32
 Node Version:              15.5.0
 Framework Version:         2.18.0 (local)
 Plugin Version:            4.4.2
 SDK Version:               2.3.2
Components Version:        3.4.6

Code (index.ts)
const serverless = require(‘serverless-http’);

import AWS from ‘aws-sdk’;

import express from ‘express’;

import bodyParser from ‘body-parser’

var dynamodb = require(‘serverless-dynamodb-client’);

const app = express()

app.use(bodyParser.urlencoded({ extended: true }));



console.log(‘setting up express’)

app.get(’/test’, (req, res) => {

console.log(‘in GET’)

res.send(‘Get Hello World!’)

})’/test’, (req, res) => {

console.log(‘in POST’)

res.send(‘Post Hello World!’).end()


module.exports.handler = serverless(app);

I am also facing this issue. Has anyone been able to figure out what the cause is?
