Hi. I am fairly new to FME, and I am doing my own practice exercise generated by AI, and everything was going swimmingly until I hit a bit of a snag.

 

I have 585 vehicles and out of all vehicle type I have 12 vehicles that are unknown so I need to change the blank value to Unknown so I use the NullAttributeMapper to do that but for some reasons, its not making any changes. Anyone know why? Would appreciate help. Thanks!

vehicle_type_clean is a different attribute than vehicle_type, you selected vehicle_type_clean, which is empty and not null.
