I have been trying to to the storage object from the material handling library in my process simulation, but whenever my agent (forklift) puts in one pallet of cargo into my storage, i get this error:
Exception during discrete event execution:
Cannot invoke “com.anylogic.engine.markup.Level.getSpace()” because “” is null
java.lang.NullPointerException: Cannot invoke “com.anylogic.engine.markup.Level.getSpace()” because “” is null
at com.anylogic.libraries.modules.level_system.LevelDataStorage.getLevelData(Unknown Source)
at com.anylogic.libraries.material_handling.LevelSystem.(Unknown Source)

I can’t seem to find this function in the java code for main or simulation. Does anyone know what this problem is?
