It wasn't coming out before, but I've been getting this error for about 1 day.
I use fingerprint, I have a mobile ip farm, everything is fine.
how can i prevent this?
In case anyone else encountered this problem. You have to edit your function and check the "has return value" box. Then your return will work. After this you have to use "Call Function" again and now you have a new field for saving results.
