Getting diffrent response from axios and postman app

[someshkoli]

Describe the bug
While using axios i noticed that axios is giving different response as expected and as obtained in postman app. the data object had some additional parameters. i have added response obtained form both the applications below and also attached the collection and the code snippet i used to run the request.

To Reproduce
run the below code snippet on nodejs and then run the bellow collection in postman app and check the output result
postman collection

var axios = require('axios');
axios.post('https://postman-echo.com/post', {
  'headers': {
    'Content-Type': 'text/plain'
  },
  body: "Duis posuere augue vel cursus pharetra. In luctus a ex nec pretium. Praesent neque quam, tincidunt nec leo eget, rutrum vehicula magna.\nMaecenas consequat elementum elit, id semper sem tristique et. Integer pulvinar enim quis consectetur interdum volutpat. !@#$%^&*()_+-=,.<>/?"

}).then((response) => {
        console.log(response.data);
}).catch((err) => {
        console.log(err);
});

Expected behavior
to get response data as shown below

{
    "args": {},
    "data": "Duis posuere augue vel cursus pharetra. In luctus a ex nec pretium. Praesent neque quam, tincidunt nec leo eget, rutrum vehicula magna.\nMaecenas consequat elementum elit, id semper sem tristique et. Integer pulvinar enim quis consectetur interdum volutpat. !@#$%^&*()_+-=,.<>/?",

When sending post requests, notice that the second parameter is data, instead of axios config. See more in my notes.
