Notes
If you draw a stream flow from a Mapper logic that does not belong to the condition category to the second input handler (lower connecting line), when you execute the script, an unexpected conversion result may be output.
Therefore, when you draw the stream flow to the second input handler, draw from a Mapper logic that belongs to the condition category.
Example of logic use
Mapping definition
