Firestore orderBy descending is not working

When using Firestore I get an error only when I use .orderBy
error message is:
Uncaught Error in snapshot listener: [FirebaseError: no matching index found.]

todoRef
      .where("owner", "==", firebase.auth().currentUser.uid)
      .where("date", "==", props.date)
      .orderBy("description", "desc")
      .onSnapshot((querySnapshot) => {
        const data = [];
        querySnapshot.forEach((doc) => {
          const d = {
            id: doc.id,
            ...doc.data(),
          };
          data.push(d);
        });
        //console.log("coming from function", data);
        setData(data);
        return data;
      });

ANDROID On your terminal type:

adb logcat

or open logcat on Android studio, you will find a log with the error, reporting the url to create automatically the index required.

IOS Open xCode, go to logs and you will find a log with error, reporting the url to create automatically the index required.

If the url doesn't show, it's a known bug on firebase sdk. Follow this issue to get any update: https://github.com/firebase/firebase-js-sdk/issues/5152

If you don't want to wait just create manually the index with the console.

You need to create the index in your firebase console. Copy the link that has been printed into the console.
