Could you provide the code you're using to reproduce this error?

[SandroCoutinho]

import org.rev317.min.api.methods.Npcs;

public class Attack implements org.parabot.environment.scripts.framework.Strategy {

    @Override
    public boolean activate() {
        Npcs.getNearest(npc -> npc.getDef().getId() == Constants.SHADOWKING_ID)

        return false;
    }

    @Override
    public void execute() { }
}

FYI: Updated your code to only provide code regarding the error.

What is the desc value of the id field of NpcDef in the client?

A way to fix this issue is to surround Npc.getNearest with a try/catch
Example

            try {
                Npc[] npcs = Npcs.getNearest(new Filter<Npc>() {
                    @Override
                    public boolean accept(Npc npc) {
                        return npc.getDef().getId() == Constants.AUBURY_ID;
                    }
                });
            } catch (NullPointerException ignored) {
            }
