Help with Constructing Query for Edge Property Ordering

[oladotunbindy]

Hi, thanks for this wonderful library as it has helped a lot while using Gremlin. I have an inquiry on writing this gremlin query with Gremlinq.

The goal of this query is to get a user's followers ordered by a createdAtTimestamp property which exists on the Follower Edge.
Below is the raw Gremlin query I believe should achieve this. Ignore the default Guid.

g.V().has('id', '00000000-0000-0000-0000-000000000000')
  .inE('Follower')
  .order()
  .by('CreatedAtTimeStamp', decr)

This is my attempt on writing this with Gremlinq, but this has not been successful as I can't properly navigate with the methods and I have compiler errors .
" IOrderBuilderWithBy<IVertexGremliQuery>' does not contain a definition for 'ToArrayAsync' and no accessible extension method 'ToArrayAsync' accepting a first argument of type 'type' IOrderBuilderWithBy<IVertexGremliQuery> could be found".
I would appreciate any help/pointers in writing out this query?

    public async Task<List<User>> ListInUserRelationsAsync<TEdge>(Guid userId)
        where TEdge : BaseEdge
        => (await G.V<SocialUser>(userId.ToString())
                .In<TEdge>()
                .OfType<SocialUser>()
                .Order(su => su.ByDescending(e => e.InE<TEdge>().OfType<Follower>().Order(_ => _.ByDescending(x => x.CreatedAtTimeStamp)))
                .ToArrayAsync())
            .Select(Converter.Convert)
            .ToList();
