I’m using the Java Firestore library to access my Firestore database. I am making this Query:

Query chatQuery = firestore.collection("chats")
  .whereEqualTo("userId", userId)
  .orderBy("seq", Query.Direction.ASCENDING);

// userId is already defined.

When I run it, it gives this error:

io.grpc.StatusRuntimeException: FAILED_PRECONDITION: The query requires an index. You can create it here: https://console.firebase.google.com/v1/r/project/...

However, my firestore index for the collection chats exists:

How do I fix this?
