Do you think keypress is what is making it crash because the rest of the points do not result in a server crash besides the setpackethandled also i do call setpackethandled at the end of the handle method

I was following a tutorial and another forum post on here and I have been trying to get potion effects to activate with the press of a button and every time i try a single player world the game crashes Key,KeyBinding,Packet Classes public class key { private final int key; public key(int keyIn) { this.key = keyIn; } public static void encode(key msg, PacketBuffer buf) { buf.writeInt(msg.key); } public static key decode(PacketBuffer buf) { return new key(buf.readInt()); } public static void handle(key msg, Supplier<NetworkEvent.Context> ctx) { if(msg.key==0) { ctx.get().enqueueWork(() -> { ServerPlayerEntity sender = ctx.get().getSender(); sender.addPotionEffect(new EffectInstance(Effect.get(5),20)); }); } ctx.get().setPacketHandled(true); } } @Mod.EventBusSubscriber(modid = DungeonWars.MOD_ID, bus = Mod.EventBusSubscriber.Bus.FORGE, value = Dist.CLIENT) public class keyBind { static KeyBinding[] keyBindings = new KeyBinding[]{new KeyBinding("key.strong", KeyConflictContext.UNIVERSAL, InputMappings.Type.KEYSYM, 33, "key.categories.strong")}; static Boolean keyPress = false; @SubscribeEvent public static void onTick(TickEvent.ClientTickEvent event) { if (keyPress && !keyBindings[0].isKeyDown()) { keyPress = false; } } @SubscribeEvent public static void onInput(InputEvent.KeyInputEvent event) { if (event.getKey() == keyBindings[0].getKey().getKeyCode() ) { // CrudeTechMod.log("pressed"); Packets.INSTANCE.sendToServer(new key(0)); keyPress = true; } } public static void registerKeyBindings() { for (int i = 0; i < keyBindings.length; i++) { ClientRegistry.registerKeyBinding(keyBindings[i]); } } public class Packets { private static final String PROTOCOL_VERSION = "1"; public static final SimpleChannel INSTANCE = NetworkRegistry.newSimpleChannel( new ResourceLocation(DungeonWars.MOD_ID, "main"), () -> PROTOCOL_VERSION, PROTOCOL_VERSION::equals, PROTOCOL_VERSION::equals ); public static int i=0; } //(Main) private void setup(final FMLCommonSetupEvent event) { // some preinit code Packets.INSTANCE.registerMessage(Packets.i++, key.class, key::encode, key::decode, key::handle); } private void doClientStuff(final FMLClientSetupEvent event) { // do something that can only be done on the client keyBind.registerKeyBindings(); //ClientRegistry.registerKeyBinding(keybinding); } Log java.lang.RuntimeException: Why did the advancements not load yet?!
