Title: Fixes #1520 Check for null object before accessing it

This is not related to the thor changes but a side effect of the fix for #806 which had to do with displaying optional attributes not present in the environment. In this case, slavesPerNode is a required attribute, which
caused a variable evaluate to null. Added a check for null object before accessing it.
