data/scripts/cooking.lua:111

local function GetIngredientData(prefabname)
    local name = aliases.prefabname or prefabname

But aliases table doesn't have prefabname field — probably aliases.prefabname should be aliases[prefabname] instead. Luckily prefab name is translated in GetIngredientValues() right before passing it to GetIngredientData():

        local name = aliases[v] or v
        prefabs[name] = prefabs[name] and prefabs[name] + 1 or 1
        local data = GetIngredientData(name)

hence this error is neglible, provided GetIngredientData() is not used anywhere else.
