With @risingstack/graffiti-mongoose": "^5.0.9" I can run the query.
However still get some errors messages. Looks like this will be fully resolved with #100

Hey,
I'm getting this error when trying simple pagination from GrapihQL.
I'm on grafitti-mongoose 5.0.10 and as far as I can tell this is not resolved by #100.

The mongoose schema I am using (reduced for brevity):

var itemSchema = Schema({
  title: String,
  description: String,
  slug: String,
  tags: String,
  updatedAt: { type: Date, default: Date.now },
  relatedItems: [{ type: Schema.Types.ObjectId, ref: 'Item' }]
});

And the query resulting in the error:

{
  items(id: "570a6a89d675be1c3006dac8") {
    _id
    relatedItems(first: 2, after: "Y29ubmVjdGlvbi41NzBhNmE4OWQ2NzViZTFjMzAwNmRhY2E=") {
      edges {
        cursor
        node {
          _id
        }
      }
    }
  }
}

Let me know if I can provide any more information on this problem.
