"an entity cannot be saved"

[doxifieq]

on damage:
    attacker is a player
    victim is a player
    set damage to 0

    set {attacker::%uuid of victim%} to attacker

on death:
    if {attacker::%uuid of player%} is set:
        broadcast "{@logo} &b%player% &7was knocked into the void by &b%{attacker::%uuid of player%}%"
        delete {attacker::%uuid of player%}
    else:
        broadcast "{@logo} &b%player% &7died"
        delete {attacker::%uuid of player%}

the script above works perfectly fine, however i'm greeted with this message upon reloading the script.

is there a way to prevent this?

i figured it out, you can go into config.sk inside skript and set "disable variable will not be saved warnings" to true.

It’s just a warning. Your code should still work fine. I wouldn’t disable it because sometimes warning can help you know why something doesn’t work.

the entity wont be saved in the variable when the server stops or restarts.
