Missing cache even when data is present

[elilabes]

We are using Urql's offlineCache with the following (relevant) config:

export const cache = offlineExchange<GraphCacheConfig>({
  schema,
  storage,
  keys: {
    Me: () => null,
    NotificationsPaginated: () => null,   
  },
});

We have a query like this:

query totalUreadNotifications {
  me {
    notifications {
      totalUnread
    }
  }
}

The path to the data is Query.Me.NotificationsPaginated.totalUnread . This data does exist in the offline cache, however none of it has an Id.

• Query is the top level.
• Me is a container for any user authenticated data, the users id existing under Profile, but not Me.
• NotificationsPaginated is a container that has edges and pageInfo for relay.

I am wondering if this is expected to work with the cache? My understanding is that Me and NotificationsPaginated should be squashed into the parent key becoming Query.Me.NotificationsPaginated which can then read totalUnread.

The behaviour we are seeing though, is that it doesn't return the cached data and instead fetches it from the server.
