How can I upload this multidirectional array to the localstorage but without it appearing without properties?

for (let i = 0; i < uniqueUsers.length; i++) {
      var data = [];
      var y = 0;
      console.log(uniqueUsers[i])
      db.collection("stories").where("name", "==", uniqueUsers[i]).get().then((querySnapshot) => {
        y++
        var temp = [];
        querySnapshot.forEach((doc2) => {
          temp.push(doc2.data())
        })
        data.push(temp);
      }).catch((err) => {
        alert(err)
      })
    }
localStorage.setItem("hUsers", JSON.stringify(data));
console.log(data)
