Unable to query for MongoDB ObjectIDs #1518

I recently updated from 0.13.2 to 14.0.2 which includes breaking changes.

This introduced errors with existing queries which include MongoDB Object Ids (probably from #1382):

ID cannot represent value: { _bsontype: "ObjectID", id: <Buffer 5b 96 3d bf 98 0a 04 09 85 c6 6e a1> }

Repository with complete, minimal repeatable example here:

const Thing = mongoose.model('Thing', new mongoose.Schema({
  id: mongoose.Schema.Types.ObjectId,
  name: String
}));

const ThingType = new GraphQLObjectType({
  name: 'thing',
  fields: function () {
    return {
      id: { type: GraphQLID },
      name: { type: GraphQLString }
    }
  }
});

const RootMutation = new GraphQLObjectType({
  name: 'CreateMutation',
  fields: {
    create: {
      type: ThingType,
      description: 'Create new thing',
      args: {
        name: {
          name: 'Name of Thing',
          type: new GraphQLNonNull(GraphQLString)
        }
      },
      resolve: (root, args) => {
        const newThing = new Thing({ name: args.name });
        newThing.id = newThing._id;
        return new Promise((res, rej) => {
          newThing.save(err => {
            if (err) return rej(err);
            res(newThing);
          });
        });
      }
    }
  }
});
