And the same code is working perfectly fine in SWI-prolog If, for some reason, some other error comes up, and this applies to any part of the process rule, It will print out "Unknown Error:", display the error information, and stop running subtraction.

existence_error(+ObjectType, +Culprit, +Set) Culprit is of the correct type and correct domain, but there is no existing (external) resource of type ObjectType that is represented by it in the provided set. The thrown exception term carries a formal term structured as follows: existence_error(ObjectType, Culprit, Set) Compatibility
