Welcome to the RingCentral Community

Hello,

I'm using Sending Fax Demo code and receiving an error while sending a fax.

Error: 404 Not Found

Here is the code I am using.

const RC = require('@ringcentral/sdk').SDK
const http = require('https')

RECIPIENT = '+17...13'

RINGCENTRAL_CLIENTID = 'MY_ID'
RINGCENTRAL_CLIENTSECRET = 'MY_SECRET'
RINGCENTRAL_SERVER = 'https://platform.devtest.ringcentral.com'

RINGCENTRAL_USERNAME = '+142...46'
RINGCENTRAL_PASSWORD = 'MY_PASSWORD'
RINGCENTRAL_EXTENSION = '101'

var rcsdk = new RC( {server: RINGCENTRAL_SERVER, clientId: RINGCENTRAL_CLIENTID, clientSecret: RINGCENTRAL_CLIENTSECRET} );
var platform = rcsdk.platform();

platform.login( {username: RINGCENTRAL_USERNAME, password: RINGCENTRAL_PASSWORD, extension: RINGCENTRAL_EXTENSION} )

platform.on(platform.events.loginSuccess, function(e){
  send_fax()
});

async function send_fax() {
  var FormData = require('form-data');
  formData = new FormData();
  var body = {
    to: [{'phoneNumber': RECIPIENT}],
    faxResolution: 'High',
    coverPageText: "This is a demo Fax page from Node JS"
  }

  formData.append('json', new Buffer.from(JSON.stringify(body)), {
    filename: 'request.json',
    contentType: 'application/json'
  });

  formData.append('attachment', require('fs').createReadStream('logo.jpeg'));

  try {
    var resp = await platform.post('/account/~/extension/~/fax', formData)
    var jsonObj = await resp.json()
    console.log("FAX sent. Message status: " + jsonObj.messageStatus)
  } catch(e) {
    console.log(e.message)
  }
}

Here is the detailed error.
