How to use the jaeger-client.RemoteReporter function in jaeger-client

'use strict'

const opentracing = require('opentracing')
const jaeger = require('jaeger-client')

// Using UDP
const UDPSender = require('jaeger-client/dist/src/reporters/udp_sender').default

const app = express()
const port = process.env.PORT || 3002

// Tracer
const udpSender = new UDPSender()
const reporter = new jaeger.RemoteReporter(udpSender)
const sampler = new jaeger.RateLimitingSampler(1)
const tracer = new jaeger.Tracer('service 1', reporter, sampler)

app.get('/', (req, res) => {
  const span = tracer.startSpan('http_server')
  span.setTag(opentracing.Tags.HTTP_URL, `${req.protocol}://${req.hostname}${req.originalUrl}`)
  span.setTag(opentracing.Tags.HTTP_METHOD, req.method)
  span.setTag('request_path', req.route.path)
  span.setTag('request_id', req.headers['x-request-id'])

  const requestOptions = {
