FUNL0112 Invalid argument number (arg number): it must be (requirement).
The FUEL compiler detected an invalid #function call, the Fast/Unload run will be cancelled. The argument number (zero for the #function result) is given in arg_number, while requirement indicates the detected requirement that was violated, as follows:
- supplied
- the #function declared the argument as required, but none was provided, or
- a %variable
- the #function declared the argument as an output argument, which means it must be a %variable.
