GatherDataEvent not firing when runData

[Darkorg69]

Spoiler

@Mod.EventBusSubscriber(modid = BetterLeveling.MOD_ID, bus = Mod.EventBusSubscriber.Bus.MOD)
public class ModEvents {
    @SubscribeEvent
    public void gatherData(GatherDataEvent event) {
        DataGenerator generator = event.getGenerator();
        PackOutput packOutput = generator.getPackOutput();
        ExistingFileHelper existingFileHelper = event.getExistingFileHelper();
        CompletableFuture<HolderLookup.Provider> lookupProvider = event.getLookupProvider();

        ModBlockTagsProvider blockTagsProvider = new ModBlockTagsProvider(packOutput, lookupProvider, existingFileHelper);

        generator.addProvider(event.includeServer(), blockTagsProvider);
        generator.addProvider(event.includeServer(), new ModItemTagsProvider(packOutput, lookupProvider, blockTagsProvider, existingFileHelper));
        generator.addProvider(event.includeClient(), new ModLanguageProvider(packOutput, "en_us"));
    }
}

 

When I do runData, it doesn't show any errors and it says that all providers took 0ms to finish. It just broke after updating to 1.19.3

PS: fixed, problem was method was not static.
