Biome Generation (Fabric 1.19.2)

Hi, every time I try and generate a custom biome it is unable to generate. I have Fabric Essentials API installed. I was never able to get TerraBlender to work, it never showed up under "External APIs" list. Here are the errors I kept getting in the console when I try to build (this is without terrablender installed):
