java.lang.ClassNotFoundException: SCESession

[avc902565906270]

I got this error while trying to simulate my app on OD. I check the availability of SCESession class since the log told that the class is not found. But the SCESession class is there. Any idea what I need to check so I can test my application locally before deployment?
