Error: _id.map is not a function

[yoadsn]

Hey, I'm getting this error when trying simple pagination from GrapihQL. I also posted this on #90 but since it's closed - I think no one would look at it now. 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.

"graphql": "^0.5.0",
"mongoose": "^4.4.12"
"@risingstack/graffiti": "^3.0.3",
"@risingstack/graffiti-mongoose": "^5.0.10",

Works for me. Do you have all items in the other table (required to complete the query)?

I also have this error when trying to implement pagination. I have a connection which I am trying to load more results. There are 22 nodes in my edge and if i query 6, then onclick request +6 more I get the error. With initial variables at 25 or any number there is no issue, only when updating relay variables. Anyone see what I could be doing wrong?

Inside the header this is the error {statusCode: 400, error: "Bad Request", message: "_id.map is not a function"}

The component

class CardImageList extends React.Component {
  render() {
    var currentNumber = this.props.relay.variables.limit;
    var buttonStyle = {};
    if (!this.props.content.pages.pageInfo.hasNextPage) {
      buttonStyle.display = 'none';
    }

    return (
      <div>
        <Grid>
          {this.props.content.pages.edges.map((edge, index, arr) =>
            <Cell>
              <CardImageListItem page={edge.node} />
            </Cell>
          )}
        </Grid>
        <div>
          <button
            style={buttonStyle}
            onClick={() => this.props.relay.setVariables({limit: currentNumber + 6})}>
            load more
          </button>
        </div>
      </div>
    );
  }
};

export default Relay.createContainer(Radium(CardImageList), {
  initialVariables: {
    limit: 6
  },
  fragments: {
    content: () => Relay.QL`
      fragment on Content {
        pages(first: $limit) {
          edges {
            cursor
            node {
              ${CardImageListItem.getFragment('page')}
            }
          },
          pageInfo {
            startCursor
            endCursor
            hasPreviousPage
            hasNextPage
          }
        }
      }
    `,
  }
});
