Importing the library doesn't work!

Hello everyone Such a problem: on version Mcreator 2023.2, when creating a procedure with the opening of the GUI, an error appears after compilation - OpenProcedure.java:53: error: cannot find symbol 
return new VillagerguiMenu(id, inventory, new FriendlyByteBuf(Unpooled.buffer()).writeBlockPos(_bpos));

The solution is simple lock the element and import the component: import io.netty.buffer.Unpooled;

But this has never happened before! Please solve it!
