Code:

PacketContainer container = new PacketContainer(PacketType.Play.Server.REMOVE_ENTITY_EFFECT);
        container.getIntegers().write(0, player.getEntityId());
        container.getEffectTypes().write(0, PotionEffectType.SLOW_DIGGING); // <---- exception here

This server is running Paper version git-Paper-"10e9c5a" (MC: 1.17) (Implementing API version 1.17-R0.1-SNAPSHOT)

On normal Spigot seems to work fine, only Paper is affected.

Spigot MobEffectList:

    public static MobEffectList byId(int rawId) {
        return (MobEffectList)IRegistry.V.fromId(rawId);// 37
    }

Paper MobEffectList:

    public static MobEffectList fromId(int i) {
        return (MobEffectList)IRegistry.V.fromId(i);// 39
    }

@LoneDev6 should be fixed in the latest dev build
