Issue when creating SPA

[robshelly]

When using this package in standalone node scripts everything works as expected. However, when trying to use it to implement an SPA (I'm using React) it throws the following error:

Uncaught (in promise) TypeError: Cannot read property 'remoteAddress' of undefined
  at module.exports.<anonymous> (client.js:535)
  at module.exports.EventEmitter.emit (events.js:81)
  at module.exports.ClientRequest._connect (request.js:247)
  at request.js:140
  at <anonymous>

Not sure what's causing it so I'm unsure if it's an issue with the node-jenkins package.
