[1.16.4] I need help to fix an IllegalArgumentException

[Megaton_216_]

A while ago I made a tool that cycles through blockstates on fabric. I am trying to do the same thing in forge but I get this error:

java.lang.IllegalArgumentException: Cannot set property IntegerProperty{name=decor, clazz=class java.lang.Integer, values=[0, 1, 2, 3]} as it does not exist in Block{null}

 

I'm not sure what the error is in my code so im asking for help

 

My code:

 

import net.minecraft.block.Block;
import net.minecraft.block.BlockState;
import net.minecraft.state.IntegerProperty;
import net.minecraft.state.StateContainer;

public class DecorableBlock extends Block{
    
    public static final IntegerProperty DECOR = IntegerProperty.create("decor", 0, 3);
        
    public DecorableBlock(Properties properties) {
        super(properties);
        setDefaultState(getStateContainer().getBaseState().with(DECOR, 0));
    }

    protected void appendProperties(StateContainer.Builder<Block, BlockState> stateContainer) {
        stateContainer.add(DECOR);
    }
}

I'm pretty sure you are overriding the wrong method, it should be fillStateContainer or something in the latest version.
