The error you are receiving is because debug function don't know about a parameter startupinfo.
It's even stranger because I looked into the utility.py of logi85 and there is no debug function at all but the good old log.

So wether you uncommon to it because it is not necessary for the function or you try to delete the the ", startupinfo=info" and try again.
If the last is not working also rename utility.debug to utility.log and delete the startupinfo parameter also.
