Sorry, late to this discussion but if the error happens inside a function node, doesn't that crash the VM? If so, can't the VM itself be wrapped in a try/catch? Not sure that would catch everything but it might help?
Sorry if that is just too simplistic, I've not had a chance to look at the core code where the VM is set up.
Also, am I the only one who spotted the typo in the error message? "seams" should be "seems" - is that message from the browser or from Node-RED?
