getter for WorldGuard flags - Via Skript-reflect

[zahrajsi.net]

Mc Version : git-Purpur-1613 (MC: 1.18.2)
Skript ver: 2.6.1

hello I have a problem with this code, no matter what I do it still gives me the same error, I would like to make a snipset out of it but at the moment I can't move on either way,

what exactly is it supposed to do?

Returning a flag value for example the flag status "pvp" and it will return "deny or allow" or "true or false"

Thank you so much for the help..
I'm already desperate.
The code

import:
    org.bukkit.Bukkit
    com.sk89q.worldguard.bukkit.WorldGuardPlugin
    com.sk89q.worldguard.util.Enums
on load:
    set {world} to "main" parsed as world

command 333:
    trigger:
        set {loc} to new Location({world}, 10, 64, 100)
        set {_container} to (class "com.sk89q.worldguard.WorldGuard").getInstance().getPlatform().getRegionContainer()
        broadcast "&cDebug[CONTAINER]: &e%{_container}%"
        set {_query} to {_container}.createQuery()
        broadcast "&cDebug[emptyQuery]: &e%{_query}%"

        broadcast "&cDebug: &e%{_query}.testState({loc}, player, Flags.PVP)%"

function wgFlag(flag: string, region: string, s: sender) :: string:
    set {result} to {query}.testState({_region}, {_s}, Enum.valueOf(Flags.%{_flag}%))
    if {result} is "allow":
        return "allow"
    else:
        return "deny"
