Can't use @Permission on class

[Tenebrosful]

Hi, i'm trying to use @Permission decoration to make a Group Slash with a role permission but it always throw me this error

D:\depotsGit\Bot-Discord-IUT-Nancy-Charlemagne\node_modules\reflect-metadata\Reflect.js:544
                        throw new TypeError();
                              ^

import { Discord, Slash, Group, Description, Permission } from "@typeit/discord";
import { CommandInteraction, TextChannel } from "discord.js";

@Discord()
@Permission("753182939352793138", 'ROLE')
@Group("maintenance", "Commandes de maintenance réservées aux Admins")
abstract class maintenance {
    @Slash('purgeChannel')
    @Description("Clone et supprime le salon afin de supprimer son contenu")
    private purgeChannel(interaction: CommandInteraction) {
        const channel = <TextChannel>interaction.channel;

        channel.clone({ reason: `Purge du salon demandé par ${interaction.user.username}` });
        channel.delete(`Purge du salon demandé par ${interaction.user.username}`);
    }
}

I also tried with the doc example

import { Discord, Permission, Slash } from '@typeit/discord';

@Discord()
@Permission("227882902031958016", "USER") // Only the role that has this USER_ID can use this command
@Permission("753182939352793138", "ROLE") // Only the role that has this ROLE_ID can use this command
class DiscordBot {
  @Slash("hello") // Only the role that has this ROLE_ID can use this command
  private hello(
  ) {
    // ...
  }

  @Slash("hello2") // Only the role that has this ROLE_ID can use this command
  private hello2(
  ) {
    // ...
  }
}

But it throw the same error.

Thx in advance <3

PS: Idk if it's linked but i can't use multiple @Permission, it only take the last, maybe i will create a different issue for that
