IBM Watson Visual Recognition (NodeJS) - Error code 403 : Forbidden: Access is denied due to invalid credentials

I am currently using Watson Visual Recognition API in the environment below but getting 403 invalid credential error. For your information I am running this on Ubuntu Server 16.04.6 LTS in VMware Workstation 15.5.1. The Node js code is from IBM Cloud webpage in below URL and I input the api key in my credentials. I already installed npm by using following command and following the guide.

npm install --save watson-developer-cloud

var VisualRecognitionV3 = require('watson-developer-cloud/visual-recognition/v3');
var fs = require('fs');

var visualRecognition = new VisualRecognitionV3({
  version: '2018-03-19',
  iam_apikey: 'Hy-N8Lxxxxxxxxxxxxxxxxxxxxxxxxxxxx'  // used api key in my credentials
});

var url= 'https://watson-developer-cloud.github.io/doc-tutorial-downloads/visual-recognition/640px-IBM_VGA_90X8941_on_PS55.jpg';

var params = {
  url: url,
};

visualRecognition.classify(params, function(err, response) {
  if (err) {
    console.log(err);
  } else {
    console.log(JSON.stringify(response, null, 2))
  }
});

When I execute the command node {filename}.js in the command line, I get the error message like below. For this error, the code is 403 and when I input the wrong API key, error code 400 appear so I don't think the error is on wrong api key.

Appreciated if you can help me find the solution to this problem.

Try this for lite account:

    const fs = require('fs');
    const { IamAuthenticator } = require('ibm-watson/auth');
    var VisualRecognitionV3 = require('watson-developer-cloud/visual-recognition/v3');


        var visualRecognition = new VisualRecognitionV3({
          authenticator: new IamAuthenticator({
            apikey: 'Hy-N8Lxxxxxxxxxxxxxxxxxxxxxxxxxxxx',

          }),
          url: 'https://watson-developer-cloud.github.io/doc-tutorial-downloads/visual-recognition/640px-IBM_VGA_90X8941_on_PS55.jpg',
        });

var params = {
  url: url,
};

visualRecognition.classify(params, function(err, response) {
  if (err) {
    console.log(err);
  } else {
    console.log(JSON.stringify(response, null, 2))
  }
});
