Forgot about putting the server.lua in t1ger_Shops:

-- Get player inventory limit:
ESX.RegisterServerCallback('t1ger_shops:getPlayerInvLimit',function(source, cb, data)
    local xPlayer = ESX.GetPlayerFromId(source)
    local limitExceed, DataFetched = false, false
    if #data > 0 then
        for k,v in pairs(data) do
            local invItem = xPlayer.getInventoryItem(v.item)
            if invItem ~= -1 and (invItem.count + v.count) > invItem.limit then
                limitExceed = true
                TriggerClientEvent('t1ger_shops:ShowNotifyESX', xPlayer.source, (Lang['item_limit_exceed']):format(v.label,invItem.limit))
            end
            if k == #data then DataFetched = true end
        end
    else
        local invItem = xPlayer.getInventoryItem(data.item)
        if invItem ~= -1 and (invItem.count + data.value) > invItem.limit then
            TriggerClientEvent('t1ger_shops:ShowNotifyESX', xPlayer.source, (Lang['item_limit_exceed']):format(data.name,invItem.limit))
            limitExceed = true
            DataFetched = true
        else
            DataFetched = true
        end
    end
    while not DataFetched do Citizen.Wait(5) end
    if DataFetched then if limitExceed then cb(true) else cb(false) end end
end)
