I think the issue was by ths following , I just solved this problem. I'm leaving the solution here in case it helps anyone else. In my case, I needed to alter the way I added my data to the database. Initially, I was using: DatabaseService.shared.REF_BASE.child("users").child(snap.key).child("posts").childByAutoId.setValue(parameters)
DatabaseService.shared.REF_BASE.child("users").child(snap.key).child("posts").child(key).setValue(parameters)
let key = DatabaseService.shared.REF_BASE.child("users").child(snapshot.key).child("posts").childByAutoId().key

How to remove the child node while retaining the parent firebase
Date : March 29 2020, 07:55 AM
fixed the issue. Will look into that further If you remove item3, the only child of 1234567, you will always implicitly remove 1234567 because it no longer has children. There is no such thing as an "empty node" in Realtime Database. When a node not longer has children, it is effectively gone, and when you query it, it will yield no data.

it fixes the issue You can access the data snapshots by using the getSnapshots() method inside your adapter. Like this: @Override
protected void onBindViewHolder(@NonNull QuoteViewHoler holder, int position, @NonNull Quote model) {
this.getSnapshots().getSnapshot(position).getKey();
