Custom Items not defined

[Searis]

So in the Lifesteal-SMP-Plugin the "lives" (hearts) are red dye but with NBT data, in my /dupe script if I blacklist red dye it can still be duped, but if I add the actual ingame name "heart_item" the skript runs into an error. Same with the beacon "revive_beacon" and carrot on a stick "heart_fragment_item" any way to fix this?
Here code:

options:
    blacklist: command block and bedrock and repeating command block and debug stick and player head and heart fragment item and heart item and revive beacon
    prefix: &r&2Searis Dupe | &r


command /dupe:
    cooldown: 2 seconds
    cooldown message: {@prefix} Before duping again, wait &6%remaining time%!
    cooldown bypass: dupe.cooldown.bypass
    trigger:
        if {@blacklist} contains type of tool:
            send "{@prefix} &3You may &l&4not &r&3dupe that item!"
            stop
        if lore of player's tool contains "&4Undupable":
            send "{@prefix} &3You may &l&4not &r&3dupe that item!"
            stop
        else:
            give player's tool to player
            stop


command /undupe:
    cooldown: 5 seconds
    cooldown message: {@prefix} Before unduping again, wait &6%remaining time%! %nl%&r{@prefix}If you think this is a &4mistake &rcontact a &9developer&r.
    cooldown bypass: dupe.undupe.cooldown.bypass
    trigger:
        if lore of player's tool is empty:
            set lore of player's tool to "&4Undupable"
        
        else:
            add "" to lore of player's tool
            set lore of player's tool to "%lore of player's tool% %nl%&4Undupable"

What I would recommend doing, is adding either names or item types that cannot be duped into a list variable. For example:

on load:
clear {Blacklist::*} #Can remove this section after everything is added
add command block to {Blacklist::*}
add bedrock to {Blacklist::*}
add debug stick to {Blacklist::*}
etc

command /dupe:
cooldown: 2 seconds
cooldown message: {@prefix} Before duping again, wait &6%remaining time%!
cooldown bypass: dupe.cooldown.bypass
trigger:
if {Blacklist::*} contains type of tool:
send "{@prefix} &3You may &l&4not &r&3dupe that item!" to player
stop
if lore of player's tool contains "&4Undupable":
send "{@prefix} &3You may &l&4not &r&3dupe that item!" to player
stop
else:
give player's tool to player
stop

Also, by doing this you could easily configure and check what items are blacklisted by sending the variable as a whole (Ie: send "%{Blacklist::*}% to player". I believe your issue before was inputting every blacklisted item into an option. Options I believe (Could be mistaken) are mostly used to refer back to texts/single value type inputs, you'd probably want to use a list variable to store multiple entries most effectively.
