Internal errors are really difficult to diagnose, but usually indicate some sort of internal corruption in the job. I'm assuming from some of the routines that this is a runtime error (not a compile-time error), but could you confirm that?

Have you tried saving the job to another name, recompiling and seeing if that causes the problem to go away? Sometimes that will cure job corruption.

I saved the job to another name, recompiled and it ran successfully.
