[Bug] system.util.sendMessage fails with remoteServers when payload is not a dict

Thanks for sharing!

I landed on something similar

def unwrap(object): 
	if str(object).startswith('<ArrayWrapper>'):
		object = list(object)
		object = [unwrap(item) for item in object]
	elif str(object).startswith('<ObjectWrapper>'):
		object = dict(object)
		object = {key: unwrap(value) for key, value in object.items()}
	return object

Would prefer to explicitly check for ArrayWrapper and ObjectWrapper types, but not having any luck.
