How to get a response from async fetch request? (node-tetch)

Question

I'm using node-fetch for a simple HTTP POST request but I'm unable to get a response from it? I'm getting follwoing error:

(node:7200) UnhandledPromiseRejectionWarning: FetchError: invalid json response
body at url reason: Unexpected token А in JSON at position 0

when this console.log(res.json()); code runs. Fair, this URL returns a single line string as response. Maybe console.log(res.text()); should work for me?

Nope: res.text() = [object Promise]

How do I get response from this? My code:

const fetch = require("node-fetch");
var inspect = require('eyes').inspector({maxLength: false})
async function postLendingApplication(name) {
    try {
      console.log("Processing POST Loan.");
    
        var data = {
            "name" : name
        }
        var auth = Buffer.from("login:password").toString('base64')
        console.dir('data '+JSON.stringify(data));
        console.dir('auth '+auth);
      // the await eliminates the need for .then
      const res = await fetch("url.com", {
          method: "POST",
          headers: {
            'Content-Type': 'application/json',
            'Authorization': "Basic "+auth
          },
          body: JSON.stringify(data)
      })
     console.log("res.text() = "+res.text());
     //console.log(res.json());
      return res;
   }
   catch(err) { 

    throw err
    }
}

var result= postLendingApplication("00025003")
console.log(result)

You need to use the await keyword, text() is a promise.

const response = await res.text();
console.log(response);
