Lua getting "attempt to index a nil value" but its a valid value tfs 1.2

[Zombiegod]

so i am trying to add this script CreatureEvent - [TFS 1.1] Ultimate item stat system (elements, skills, exp, loot and more) (https://otland.net/threads/tfs-1-1-ultimate-item-stat-system-elements-skills-exp-loot-and-more.229771/)

to my server, i followed the thread and did all the recommended fixes, however i am getting this error with every attack i do

Lua Script Error: [CreatureScript Interface]
data/creaturescripts/scripts/stats.lua:onHealthChange
data/lib/core/stats.lua:1715: attempt to index a nil value
stack traceback:
        [C]: in function '__index'
        data/lib/core/stats.lua:1715: in function <data/lib/core/stats.lua:1622>

Which references this part of the code function stat_onHealthChange(creature, attacker, primaryDamage, primaryType, sec - Pastebin.com (https://pastebin.com/bMxF7Nvx)

I dont know if i did something wrong, if i have a incompatibility or what. I know onHealthChange works i have another script that uses it, and disabling it changed nothing.

any help would be appreciated!
