Question

[    script:mrp-gangs] SCRIPT ERROR: @mrp-gangs/server.lua:822: attempt to index a nil value (local 'xKiller')

[ script:mrp-gangs] > handler (@ReaperAC/server.lua:5)

RegisterServerEvent('asd:onPlayerDeath')
AddEventHandler('asd:onPlayerDeath', function(data)
    if data.killedByPlayer then
        local xKiller = ASD.GetPlayerFromId(data.killerServerId)
        TriggerClientEvent('asd_gangs:playerKilled', data.killerServerId)
    end
end)
 
RegisterServerEvent('asd_gangs:sumPlayerKill')
AddEventHandler('asd_gangs:sumPlayerKill', function(id)
    local xKiller = ASD.GetPlayerFromId(id)
    MySQL.Sync.execute("UPDATE users SET kills = kills + 1 WHERE identifier = @identifier", {['@identifier'] = xKiller.getIdentifier()})
end) 

Answer 1

ASD.GetPlayerFromId() is returning nil. Are you sure data.killerServerId is valid, or even exists?

One possible solution would be to check that the player with the provided ID actually exists beforehand and, if not, then handle it differently.
