Crafting Recipe help

I've tried to use:

function Initialize(Plugin)
        cPluginManager.AddHook(cPluginManager.HOOK_PRE_CRAFTING, OnPreCraft)
 
end
 
function OnPreCraft(Player, Grid, Recipe)
    local foundNil = false
    LOG("OPC->Reading Grid for first time")
    for x=1,3,1 do
        for y=1,3,1 do
            if Grid:GetItem(x,y) == nil then
                foundNil = true
            end
        end
    end
    LOG("OPC->Done reading Grid for first time")
end

Just that code alone produces this error:
Attempted to get an invalid item from a crafting grid: (3, 3), grid dimensions: (3, 3).

It gives it once for each location on the grid except for 2,2 where I place the first item

What am I doing wrong here?
