Supabase JS RC 2 - Unable to get count of rows

Unable to get exact count with option head: true

Below code is executing but returns undefined; why?

const { data: total } = await supabase
        .from("tasks")
        .select("id", { count: "exact", head: true });
      console.log(total);

const { data: total } = await supabase
        .from("tasks")
        .select("id", { count: "exact", head: true });
      console.log(total);
