Calling a POST API fron node JS

I am a beginner with nodeJS.

What I am trying to do:

I have a POST API hosted and when I call it using postman, it gives me proper response as shown in image below:

But when I try to hit it using the NodeJS node-rest-client (https://www.npmjs.com/package/node-rest-client) it is giving me an irrelevant large object as below:

IncomingMessage {
  _readableState: 
   ReadableState {
     objectMode: false,
     highWaterMark: 16384,
     buffer: BufferList { head: null, tail: null, length: 0 },
     length: 0,
     pipes: null,
     pipesCount: 0,
     flowing: true,
     ended: true,
     endEmitted: true,
     reading: false,
     sync: true,
     needReadable: false,
     emittedReadable: false,
     readableListening: false,
     resumeScheduled: false,
     defaultEncoding: 'utf8',
     ranOut: false,
     awaitDrain: 0,
     readingMore: false,
     decoder: null,
     encoding: null },
  readable: false,
  domain: null,
  _events: 
   { end: [ [Function: responseOnEnd], [Function] ],
     data: [Function],
     error: [Function] },
  _eventsCount: 3,
  _maxListeners: undefined,
  socket: 
   Socket {
     connecting: false,
     _hadError: false,
     _handle: null,
     _parent: null,
     _host: null,
     _readableState: 
      ReadableState {
        objectMode: false,
        highWaterMark: 16384,
        buffer: [Object],
        length: 0,
        pipes: null,
        pipesCount: 0,
        flowing: true,
        ended: false,
        endEmitted: false,
        reading: true,
        sync: false,
        needReadable: true,
        emittedReadable: false,
        readableListening: false,
        resumeScheduled: false,
        defaultEncoding: 'utf8',
        ranOut: false,
        awaitDrain: 0,
        readingMore: false,

I need help to get my proper object and I am not able to figure out what I am doing wrong here.
