Ahh right this is caused by lack of new keyword, or it should use createServer instead!

@willnode it seems like this is not a unit bug. Is there anything else you need help with, or can we close this for now?

[willnode]

Yeah, this can be closed. Just pointing out for future users having this problem.

Excellent, thank you! Hope it's going to be useful for them :)
