Also seeing the same error. Same version and game client.

Seems like it's a C_Everwhere issue.
Changing the onBag event to do a nil check will fix it until there's a new version.
https://github.com/Jaliborc/Scrap/blob/master/addons/main/pricing.lua#L40-L43
Change that to:

function Prices.OnBag(tip, bag, slot)
    local info = C.GetContainerItemInfo(bag, slot)
    if info ~= nil then
        Prices:AddLine(tip, info.itemID, info.stackCount, true)
    end
end
