body: <p>I have meeting url which works on both the MAC desktop client and the web client, but when I use this url on the <a href="https://github.com/OfficeDev/skype-android-app-sdk-samples/tree/master/GuestMeetingJoin" rel="nofollow">skype for business sample app's GuessMeetingJoin</a> app, I get a response 500 error, below is the stack trace.
