An unused Function lead to error

[mnieuwland]

As soon as a Function is defined, but not used in the Predicate_Object sheet, I get the following error:

Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/runpy.py", line 196, in _run_module_as_main

    result[fun]['Source']['FunctionID'] = fun
TypeError: 'NoneType' object does not support item assignment

Why would I define a function that I'm not using?

Well I do use the function. The result of the function is used as the input for another function. That works fine, but only after I also use the first function as a 'dummy' Object in the Predicate_Object sheet, the error is gone. However, this leaves me with a dummy triple I don't really want....
