[1.20.2] custom MobEffect.applyEffectTick method not working

[ke_do]

public class FireDot extends MobEffect {

    public FireDot() {

        super(MobEffectCategory.HARMFUL, 0x660990);
        getLogger().info("Test Log 999994 ");
    }

    @Override
    public void applyEffectTick(LivingEntity entity, int amplifier) {
        if (entity instanceof LivingEntity) {

            entity.hurt(entity.damageSources().inFire(), 0.1F + amplifier);
			getLogger().info("Test Log 22333 : ")
        }


    }

    public boolean isDurationEffectTick(int duration, int amplifier) {
        int tickInterval = 2;
        return duration % tickInterval == 0;
    }
}

this is my custom MobEffect

public class ModEffects {
    public static final DeferredRegister<MobEffect> MOB_EFFECTS = DeferredRegister.create(ForgeRegistries.MOB_EFFECTS, DoJiJoJu.MODID);
    public static final RegistryObject<MobEffect> FIRE_DOT = MOB_EFFECTS.register("fire_dot", FireDot::new);
    public static void register(IEventBus eventBus) {MOB_EFFECTS.register(eventBus);}
}

and I registed in Registry

        ModEffects.register(modEventBus);

in my Main Class

            ((LivingEntity) this.target).addEffect(new MobEffectInstance(ModEffects.FIRE_DOT.get(), 100, 1));
            getLogger().info("Test Log 888884 " + ModEffects.FIRE_DOT.get());

I add the Effect by this way

and the `Log 888884` was printed

but other Logs wasn't printed.

The effect of MobEffectCategory.HARMFUL, 0x660990 was visible.

but the hurt code wasn't work

why It doesn't work? I tested in Creative mode and solo play

Thank you
