Answer 1

It looks like your using express. For express to find raw data in a request you need to use a middleware. Look into app.use(express.json()).

You don't need to require it its a built in method. It would go in your server or app.js file. This would ensure that you can access json data in the request.

it used to be called body-parser which was a popular npm package but is now available through express.

In a basic server file it might look like this

const express = require('express')
const app = express()
const port = 3000

app.use(express.json())   <----- something like this 
app.use(myrouteshere)

app.listen(port, () => console.log(`Example app listening on port ${port}!`))

Answer 2

In my case, I used app.use(express.json()) and started working prefectly.

Sometimes there could be custom content-type header value instead of just application/json. Make sure you have the right one.
