I'm guessing it's because you're not waiting for all auction items to get cached, and skip ahead to checking the auctions

Here's another example which prints the lowest price for an item ID right after it's done scanning or when you press the button or run a script

local initialQuery
local auctions = {}
local f = CreateFrame("Frame", "SomeAddon")
 
-- you can also press the button or use this script when scanning is done
-- /run print(GetMoneyString(SomeAddon:GetLowestPrice(152510)))
local btn = CreateFrame("Button", nil, UIParent, "UIPanelButtonTemplate")
btn:SetPoint("CENTER")
btn:SetSize(120, 40)
btn:SetText("Example")
btn:SetScript("OnClick", function(self, button)
    if next(auctions) then
        f:SomeExample()
    else
        print("No data")
    end
end)
 
function f:SomeExample()
    local price = self:GetLowestPrice(152510)
    print("Min Price:", GetMoneyString(price))
end
 
function f:GetLowestPrice(itemID)
    local minPrice = math.huge
    for _, v in pairs(auctions) do
        if v[17] == itemID then
            local unitPrice = v[10] / v[3] -- totalPrice / count
            --print(unitPrice)
            minPrice = min(minPrice, unitPrice)
        end
    end
    if minPrice < math.huge then
        return minPrice
    end
end
 
function f:ScanAuctions(callback)
    local continuables = {}
    wipe(auctions)
    for i = 0, C_AuctionHouse.GetNumReplicateItems()-1 do
        auctions[i] = {C_AuctionHouse.GetReplicateItemInfo(i)}
        local item = Item:CreateFromItemID(auctions[i][17]) -- itemID
        continuables[item] = true
 
        item:ContinueOnItemLoad(function()
            auctions[i] = {C_AuctionHouse.GetReplicateItemInfo(i)}
            continuables[item] = nil
            if not next(continuables) then
                print("I'm done scanning")
                callback()
            end
        end)
    end
end
 
function f:OnEvent(event)
    if event == "AUCTION_HOUSE_SHOW" then
        C_AuctionHouse.ReplicateItems()
        initialQuery = true
    elseif event == "REPLICATE_ITEM_LIST_UPDATE" then
        if initialQuery then
            self:ScanAuctions(function() self:SomeExample() end)
            initialQuery = false
        end
    end
