Postman Express.js Response Body is always empty

Question

I have been stuck on this problem for a day. I cannot solve.

I have a VERY simple node app.

const express = require("express");
const port = 3001;
const app = express();

app.use(express.json());

app.post('/', (req, res, next) => {
    console.log("Body: ", req.body);
    res.json(req.body);
})

app.listen(port);
console.log(`Serving at http://localhost:${port}`);

If I run this in a browser using any code extracted from Postman - it returns the expected result:

Body:  { test: 'defrejbar',
  email: '[email protected]',
  password: '43747638bar' }

However, if I run the EXACT same function directly from Postman, I receive an empty response.

I have tried adding body-parser, however that did not work. The only solution I have, would be to resort to Param Queries (which work), however I would prefer to be running with Response Body.

Any help would be greatly appreciated.

Answer 1

@Reyno Pointed me in the right direction.

There was no issue with the code - it was a Postman issue. I'm not sure of the exact setting, but all I did was create a new Collection and added a new Request. The only difference between the 2 collections, is the old one has a heap of existing Requests - each with different endpoint.

Weird... but it worked. Hope it helps someone else out there with the same issue.

Answer 2

I also faced the same issue but when I select x-www-form-urlencoded of postman it displays my response body.
