I have followed a tutorial on how to generate ores for my mod though the data files have not been generated despite me running data in my IDE. I have looked over and compared my code multiple times and the only differences are either with the IDs or with unnecessary code because of what my mod is (The mod is for the End so I don't need the Overworld or Nether ores), my folders are all in the right structure and no warnings are present when ran. I have been trying to figure this out for a few days now so help would be much appreciated. The tutorial I was following. My code - public class ModBiomeModifiers { public static final ResourceKey<BiomeModifier> ADD_GAZITE_ORE = registerKey("add_gazite_ore"); public static final ResourceKey<BiomeModifier> TRANSCENDINE_GAZITE_ORE = registerKey("add_transcendine_ore"); public static void bootstrap(BootstrapContext<BiomeModifier> context) { var placedFeature = context.lookup(Registries.PLACED_FEATURE); var biomes = context.lookup(Registries.BIOME); context.register(ADD_GAZITE_ORE, new ForgeBiomeModifiers.AddFeaturesBiomeModifier( biomes.getOrThrow(BiomeTags.IS_END), HolderSet.direct(placedFeature.getOrThrow(ModPlacedFeatures.GAZITE_ORE_PLACED_KEY)), GenerationStep.Decoration.UNDERGROUND_ORES)); context.register(TRANSCENDINE_GAZITE_ORE, new ForgeBiomeModifiers.AddFeaturesBiomeModifier( biomes.getOrThrow(BiomeTags.IS_END), HolderSet.direct(placedFeature.getOrThrow(ModPlacedFeatures.TRANSCENDINE_ORE_PLACED_KEY)), GenerationStep.Decoration.UNDERGROUND_ORES)); } private static ResourceKey<BiomeModifier> registerKey(String name) { return ResourceKey.create(ForgeRegistries.Keys.BIOME_MODIFIERS, ResourceLocation.fromNamespaceAndPath(EchoingEnd.MOD_ID, name)); } } The tutorial's code - public class ModBiomeModifiers { public static final ResourceKey<BiomeModifier> ADD_ALEXANDRITE_ORE = registerKey("add_alexandrite_ore"); public static final ResourceKey<BiomeModifier> ADD_NETHER_ALEXANDRITE_ORE = registerKey("add_nether_alexandrite_ore");

I'm creating a modpack, and i just discovered that if i try to connect to a server it gives the error: Internal Exception: io.netty.handler.codec.DecoderException: java.lang.negativearraysizeexception -1 The client log: -
You just need to run the updated installer like if you were installing a new server. You can overwrite an existing install with a new version. -
