[Fabric Generator] Can't make a crop

I seem to be unable to make a crop that's able to grow with the Fabric Generator 1.20.1.

I referenced the tutorial crop project and managed to recreate it perfectly as it should be, however when I go to build, it keeps throwing this set of errors.

This is the function created for crops to grow.

Am I doing something wrong, or are NBT tags just not supported by the Fabric Generator and I'm out of luck for making crops?
