Can't find nun-file after using nunchaku in isabelle

[singhjagadish]

Hello,

I have used nunchaku on an isabelle lemma, and I get an error because of an ill-formed term (probably caused by using an own datatype, more specifically a domain). It also shows the directory where the .nun-file (nunchaku2832584.nun) of the process should be.
However, I couldn't find the file there, so my question is how to get the information of the file, as it could be helpful for using nunchaku for such a datatype.

Thanks in advance.

The nunchaku plugin is Isabelle isn't production ready yet, sorry. @blanchette would probably know more but he's quite busy these days.
