lua - garry's mod - 尝试调用全局变量 'Player' (一个表值)

当尝试启动 Garry's Mod 服务器时，我遇到了一个错误：

[ERROR] gamemodes/darkrp/gamemode/modules/base/sv_gamemode_functions.lua:227: 尝试调用全局变量 'Player' (一个表值)

1. 未知 - gamemodes/darkrp/gamemode/modules/base/sv_gamemode_functions.lua:227

sv_gamemode_functions.lua:217-230

function GM:EntityRemoved(ent)

self.Sandbox.EntityRemoved(self, ent)
if ent:IsVehicle() then
    local found = ent:CPPIGetOwner()
    if IsValid(found) then
        found.Vehicles = found.Vehicles or 1
        found.Vehicles = found.Vehicles - 1
    end
end
local owner = ent.Getowning_ent and ent:Getowning_ent() or Player(ent.SID or 0)
if ent.DarkRPItem and IsValid(owner) then owner:removeCustomEntity(ent.DarkRPItem) end
if ent.isKeysOwnable and ent:isKeysOwnable() then ent:removeDoorData() end end

请帮忙解决。
