[1.17.1] "Feature: Not a JSON object"

[Nati_Waty]

 

I want to create a feature to generate a trunk without leaves on my custom biome but when I try to create a new world or entering an existing one, I have this error :

[Render thread/ERROR]: Feature: Not a JSON object: "minecraft:spring_water"; Not a JSON object: "minecraft:patch_pumpkin"; Not a JSON object: "minecraft:patch_sugar_cane"; Not a JSON object: "minecraft:patch_grass_forest"; Not a JSON object: "minecraft:flower_default"; Not a JSON object: "minecraft:glow_lichen"; Not a JSON object: "minecraft:forest_flower_vegetation"; Not a JSON object: "vanillaenhancer:sakura_trunk"

Here are all the files related to the custom feature and biome:

Not a JSON object: "vanillaenhancer:sakura_trunk"

inside your Json Biome you are using this features:

• "minecraft:spring_water"
• "minecraft:patch_pumpkin"
• "minecraft:patch_sugar_cane"
• "minecraft:patch_grass_forest"
• "minecraft:flower_default"
• "minecraft:glow_lichen"
• "minecraft:forest_flower_vegetation"
• "vanillaenhancer:sakura_trunk"

try without this features, if you have the same error again something is wrong with your json biome
if it works fine check the names of the features
