Comet Emulator - Error on startup

[Berk]

Hey.
I'm trying to setup comet emulator with illumina cms and,i stumbled up on some errors.
Here is the error on startup:

Exception in thread "main" java.lang.IllegalArgumentException: No enum constant com.cometproject.server.game.achievements.types.AchievementCategory.İDENTİTY
        at java.base/java.lang.Enum.valueOf(Unknown Source)
        at com.cometproject.server.game.achievements.types.AchievementCategory.valueOf(AchievementCategory.java:3)
        at com.cometproject.server.storage.queries.achievements.AchievementDao.getAchievements(AchievementDao.java:39)
        at com.cometproject.server.game.achievements.AchievementManager.loadAchievements(AchievementManager.java:40)
        at com.cometproject.server.game.achievements.AchievementManager.initialize(AchievementManager.java:24)
        at com.cometproject.server.boot.CometServer.init(CometServer.java:90)
        at com.cometproject.server.boot.Comet.run(Comet.java:110)
        at com.boot.Main.main(Main.java:14)

and that error refers to:

package com.cometproject.server.game.achievements.types;

public enum AchievementCategory
{
  IDENTITY,  EXPLORE,  MUSIC,  SOCIAL,  GAMES,  ROOM_BUILDER,  PETS;
 
  private AchievementCategory() {}
}

how can I solve this? I need help asap, please.
Thanks.
