try to add this in line 236

  -- Check if the player's position is valid
  local playerPos = player:getPosition()
  if not playerPos then
    print("Player Position Not Found")
    return
  end

and change line 237 to 239 for:

  local dimension = modules.game_interface.getMapPanel():getVisibleDimension()
  local spectators = g_map.getSpectatorsInRangeEx(playerPos, false, math.floor(dimension.width / 2), math.floor(dimension.width / 2), math.floor(dimension.height / 2), math.floor(dimension.height / 2))
  local maxCreatures = battlePanel:getChildCount()
