Thanks for the alert!
Definitely direct script inquiries my way. I'll try to take a look this evening. If you have a sample After Effects file/assets you can zip up and send me, that might help if it's a case I can't reproduce.

One more thing. Some times the things that cause this error can be subtle. After you get the error, open Settings, scroll down to Log and click Open to view the Spine logs. If memory serves me, there will be more details in there like line numbers and other error details. Post or email those details along with the JSON file and that will go a long way towards getting a fix in!
Thanks.
