[1.14.4] Can't spawn an ItemEntity

I just want to spawn an Item on my mod when I right click with empty hand on a log, I make this : 

package fr.ayfri.testmod.init;

import net.minecraft.entity.item.ItemEntity;
import net.minecraft.item.ItemStack;
import net.minecraft.tags.BlockTags;
import net.minecraftforge.event.entity.player.PlayerInteractEvent;
import net.minecraftforge.eventbus.api.SubscribeEvent;

public class BlockEventHandler {

    public static final BlockEventHandler INSTANCE = new BlockEventHandler();

    @SubscribeEvent
    public void OnRightClickBlock(PlayerInteractEvent.RightClickBlock e) {

        if(e.getWorld().getBlockState(e.getPos()).getBlock().isIn(BlockTags.LOGS) && e.getEntityPlayer().getHeldItemMainhand().isEmpty()) {
            System.out.println("wood log touched");

            ItemEntity wood_piece = new ItemEntity(e.getWorld(), e.getPos().getX(), e.getPos().getY(), e.getPos().getZ(), new ItemStack(ModItems.wood_piece));
            e.getWorld().addEntity(wood_piece);

        }
        return;

    }

}

But when I right click on a log, it says "wood log touched" but it doesn't spawn any Item, can you help me to figure out why ?
