I would like to comment that almost all my builds fail with this error. I pulled the latest docker image (flogo designer) and created a hello world app and exported it. The exported json pasted below. If I attempt to build it I get a panic; invalid argument. However apps built by hand or with the cli do build. If you would like me to track down the specific difference between these json files is, just ask. I will have some time on the weekend. I would also like the error in this panic to be a little more informative if possible (though I think the argument in question is nil hence the problem)

The app:
