There is issue with the key. The same code works fine if key is ok.

var fs = require("fs");
const http = require("http");
var jwt = require("jsonwebtoken");
var uuid = require("uuid/v4");

//create a server object:

var jwt = require("jsonwebtoken");

var private_key = fs.readFileSync("./private.pem");
var header = {
  kid: "bdef4554463d8078be9af1d9de55"
};

var payload = {
  iss: "a57bb14a44455e98800d6a513953fc0",
  sub: "a57bb14a445541e98800d6a513953fc0",
  aud: "https://c2performdev.talkdeskid.com/oauth/token",
  jti: uuid(),
  exp: Math.floor(Date.now() / 1000) + 300,
  iat: Math.floor(Date.now() / 1000)
};

token = jwt.sign(payload, private_key, { header: header, algorithm: "ES256" });

console.log(token);

I following command to generate key in mac.

openssl ecparam -genkey -name secp256k1 -noout -out private.pem
openssl ec -in private.pem -pubout -out public.pem

the body is key file is as follows.

this does not match what you have done. Try correcting the key structure.
