Unable to establish an https connection to remote server which uses self signed certificate using with Node.js

Question

I am not able to connect to a remote server which uses self signed certificate from node.js.

Following is the code to connect:

var rp = require('request-promise');
var fs = require("fs"); 

var options = {
  method: 'POST',
  uri: 'https://xyz.abc.domain.com:9047/apiv2/login',
  body: {
    userName: 'username',
    password: 'password'
  },
  cert: fs.readFileSync("./xyz.pem"),
  json: true // Automatically stringifies the body to JSON
};

rp(options)
  .then(function (parsedBody) {
      console.log(parsedBody);
  })
  .catch(function (err) {
    console.log(err);
    console.error('call failed');
  });

The pem file contains the public key information of the servers SSL certificate.

The .pem file is added in root of the working directory.

The error I am getting while running this node.js code is:

Is there any way we can make node.js to establish https connection to a server using self signed certificate?

I tried with process.env["NODE_TLS_REJECT_UNAUTHORIZED"] = 0; but, still got the same error as above.
