Skript Command Not Working

[burntWaffles]

Here is my code:

command /hunter:
    trigger:
         add player to group "hunter"

command /runner:
    trigger:
        add player to group "runner"
 

on death of player:
    if player is in group "hunter" :
        give compass to the player
    else if player is in group "runner" :
        broadcast "test"
        loop all players:
            clear player's group

Whenever I try and run the /hunter or /runner command it says an internal error occurred while attempting to perform this command. What can I do to fix it? The rest of my code works fine.

Do /pl or /plugins on your server and check which plugins are red (means they are outdated)
