Hello everyone i have problem on my server, if i going up on ladder +1 i have that log in my console:

Lua Script Error: [Action Interface]
data/actions/scripts/other/teleport.lua:onUse
getNumber(). Argument -1 has out-of-range value for t: -1
stack traceback:

data/lib/core/position.lua:38: in function 'moveUpstairs'
data/actions/scripts/other/teleport.lua:4: in function <data/actions/scripts/other/teleport.lua:2>

This is my position.lua

Position.directionOffset = {
    [DIRECTION_NORTH] = {x = 0, y = -1},
    [DIRECTION_EAST] = {x = 1, y = 0},
    [DIRECTION_SOUTH] = {x = 0, y = 1},
    [DIRECTION_WEST] = {x = -1, y = 0},
    [DIRECTION_SOUTHWEST] = {x = -1, y = 1},
    [DIRECTION_SOUTHEAST] = {x = 1, y = 1},
    [DIRECTION_NORTHWEST] = {x = -1, y = -1},
    [DIRECTION_NORTHEAST] = {x = 1, y = -1}
}

function Position:getNextPosition(direction, steps)
    local offset = Position.directionOffset[direction]
    if offset then
        steps = steps or 1
        self.x = self.x + offset.x * steps
        self.y = self.y + offset.y * steps
    end
end

function Position:moveUpstairs()
    local swap = function (lhs, rhs)
        lhs.x, rhs.x = rhs.x, lhs.x
        lhs.y, rhs.y = rhs.y, lhs.y
        lhs.z, rhs.z = rhs.z, lhs.z
    end

    self.z = self.z - 1

    local defaultPosition = self + Position.directionOffset[DIRECTION_SOUTH]
    local toTile = Tile(defaultPosition)
    if not toTile or not toTile:isWalkable() then
        for direction = DIRECTION_NORTH, DIRECTION_NORTHEAST do
            if direction == DIRECTION_SOUTH then
                direction = DIRECTION_WEST
            end

            local position = self + Position.directionOffset[direction]
            toTile = Tile(position)
            if toTile and toTile:isWalkable() then
                swap(self, position)
                return self
            end
        end
    end
    swap(self, defaultPosition)
    return self
end

function Position:isInRange(from, to)
    -- No matter what corner from and to is, we want to make
    -- life easier by calculating north-west and south-east
    local zone = {
        nW = {
            x = (from.x < to.x and from.x or to.x),
            y = (from.y < to.y and from.y or to.y),
            z = (from.z < to.z and from.z or to.z)
        },
        sE = {
            x = (to.x > from.x and to.x or from.x),
            y = (to.y > from.y and to.y or from.y),
            z = (to.z > from.z and to.z or from.z)
        }
    }

    if  self.x >= zone.nW.x and self.x <= zone.sE.x
    and self.y >= zone.nW.y and self.y <= zone.sE.y
    and self.z >= zone.nW.z and self.z <= zone.sE.z then
        return true
    end
    return false
end

function Position:notifySummonAppear(summon)
    local spectators = Game.getSpectators(self)
    for _, spectator in ipairs(spectators) do
        if spectator:isMonster() and spectator ~= summon then
            spectator:addTarget(summon)
        end
    end
end

Someone can help me? I will be grateful.
Best regards.
