How To Solve Uncaught Error in snapshot listener: FirebaseError: no matching index found Error ?

Solution 1

The problem is you must create an index for your “where” and “orderBy” conditions in the indexes column in your cloud firestore.

Solution 2

That’s a known issue with Client SDKs and the Firebase team is working on it. Just use the Firebase Functions Emulator locally with the Admin SDK. Use an existing Firebase project or create a new one for this.

export const getIndexLink = functions.https.onRequest(async (request, response) => {
    try {
        const snap = const query = db.collection('iterations')
            .where('courseCode', '==', code)
            .orderBy('iterationCode', 'desc')
            .limit(1)
            .get()
        console.log(snap.size)
        response.send( snap.size, "documents matched");
    } catch (error) {
        console.log(error)
        response.send(error.message)
        // Error with index creation link
    }
});

You can try calling this function in a browser and get the index creation link.
