Hi, this is my first post, i want to share a remake i did to a function who @Summ made here
This is a function to find an item on a container or a container list, of course you could add a player to check on his/her equipment too.
Here is it:

function Game.getContainerItemsById(containerList, itemId, player)
    local containers = {}
    local items = {}
    local containerAux --temporal var to store a new container
    local itemAux  --temporal var to store new item
    
    for i = 1, #containerList do
        itemAux = containerList[i]
        if (itemAux:isContainer()) then
            table.insert(containers, itemAux)
        end
    end
  
    if (player) then
        for i = CONST_SLOT_FIRST, CONST_SLOT_LAST do
            local itemAux = player:getSlotItem(i)
            if (itemAux) then

                if (itemAux:isContainer()) then
                    table.insert(containers, itemAux)
                else
                    if (itemAux:getId() == itemId) then
                        table.insert(items, itemAux)
                    end
                end
            end
        end      
    end

    while #containers > 0 do
        local containerAux = containers[1]
        for i = 0, containerAux:getSize() - 1 do
            itemAux = containerAux:getItem(i)
            if (itemAux:isContainer()) then
                table.insert(containers, itemAux)
            else
                if (itemAux:getId() == itemId) then
                    table.insert(items, itemAux)
                end
            end
        end
        table.remove(containers, 1)
    end

    return items
end
