I am upgrading from Mongoid 6.4.8 to 7.4.0. Many changes I have been able to work through, but one persists and is causing a few issues.

How do I replace a where condition created with the `ne` method? I have a model, User. It has a default scope that, among other conditions, only selects users where they that are not preview users and have accepted their invite (datetime field invite_accepted_at).

default_scope -> { where(is_preview_user: false, blocked: false).ne(invite_accepted_at: nil) }

In some places, I need to get all users, including those who haven't accepted the invite.

User.where(invite_accepted_at: nil).count

In 6.4.8, this produced a query that looked like this:

```

```

However, in 7.4.0, this produces a query that looks like this:

```
{"is_preview_user"=>false, "blocked"=>false, "invite_accepted_at"=>

, "$and"=>[

]}
```

As you can see, the 7.4.0 is trying to get users where invite_accepted_at is both nil and not nil, resulting in no users returned.

So is there a method I can call, a change I can make, or a setting I can enable to generate the right query, namely, the later call to invite_accepted_at replaces the earlier one.

I tried:

User.override.where(invite_accepted_at: nil)

but it seems to have no effect.

Would appreciate being pointed in the right direction.
