Transition Issue post-function does not work after upgrading to jira 7

Description

I have a post-action on "Create" transition.
This post action transitions issue to a different status if Sprint field is set. Specifically:

if (issue.get("Sprint")) { return true; } else { return false; }

This transition worked great while using Jira 6. We upgraded and now when I create an issue with Sprint set I get error 500 from the server. I had to remove the post action so that I can create issues.

Here's the trace:
