Hello guys, My OTCv8 (last version from OTCv8 repo) is getting this error on log. Someone help me to fix, please? Error:

ERROR: lua function callback failed: /modules/game_battle/battle.lua:357: attempt to compare nil with number
stack traceback:
    [C]: in function '__lt'
    /modules/game_battle/battle.lua:357: in function </modules/game_battle/battle.lua:355>

Function pointed:

 function sortCreatures(creatures)
  local player = g_game.getLocalPlayer()
  
  if getSortType() == 'distance' then
    local playerPos = player:getPosition()
    table.sort(creatures, function(a, b) 
      if getDistanceBetween(playerPos, a:getPosition()) == getDistanceBetween(playerPos, b:getPosition()) then
        return ages[a:getId()] > ages[b:getId()]
      end
      return getDistanceBetween(playerPos, a:getPosition()) > getDistanceBetween(playerPos, b:getPosition()) 
    end)
  elseif getSortType() == 'health' then
    table.sort(creatures, function(a, b) 
      if a:getHealthPercent() == b:getHealthPercent() then
        return ages[a:getId()] > ages[b:getId()]
      end
      return a:getHealthPercent() > b:getHealthPercent() 
    end)
  elseif getSortType() == 'age' then

  elseif getSortType() == 'screenage' then
    table.sort(creatures, function(a, b) return a.screenAge > b.screenAge end)
  else -- name
    table.sort(creatures, function(a, b)
      if a:getName():lower() == b:getName():lower() then
        return ages[a:getId()] > ages[b:getId()]
      end
      return a:getName():lower() > b:getName():lower()
