JSON decode error

[gsteinLTU]

One of the students ran into this at the end of class. I believe it was working before then, and nothing seemed off about her code.

I can try to get the project json file from her if needed, although it looks like a cloud-related thing.

Traceback (most recent call last):

Yeah, that looks like a NetsBlox cloud error where it failed to create the project instance needed to call rpcs and receive messages. For some reason that can sometimes fail. It's just hard to debug since it's a random event and re-running it fixes the problem. But was that consistently happening for that student?

It was consistently not working after it happened once, relaunching PyBlox fixed it. It might be helpful if we can display a better error in this case at least, so it's obviously cloud that's wrong instead of PyBlox.
