TypeError: Cannot read property 'length' of undefined

Hi guys

First of all I want to thank you for this amazing app. If it works it would be much easier to transfer my spotify playlists to google music.

I pulled the actual version of portify from Github. After starting the transfer by 'node app.js' I got the following log:

TypeError: Cannot read property 'length' of undefined

    at Receiver.self._receiver.ontext (/Users/Fabian/Documents/portify/data/node_modules/spotify-web/node_modules/ws/lib/WebSocket.js:697:10)

Do you know what the problem could be?

Environment OS - OSX 10.9.1 portify ver. - 0.5.1

Same problem for me, I removed the console.log() in line 320 and get this one:

I found the solution... Spotify changed their functionality... You have to publish your playlists in spotify and then it works. For publishing rightclick on playlist and then click publish
