What is the correct type to use for an ObjectId field across mongoose and GraphQL?

Question

Following this tutorial, I have a mongoose model: (I\'m using the term \"Account\" instead of \"Todo\", but it\'s the same thing)

const Account = mongoose.m

I didn't find an issue and ran this code with one of my existing code bases. Except I wrapped the mutation in the GraphQLObjectType.

const Mutation = new GraphQLObjectType({
    name: 'Mutation',
    fields: {
        addAccount: {
            type: AccountType,
            description: 'Create new account',
            args: {
                name: {
                    name: 'Account Name',
                    type: new GraphQLNonNull(GraphQLString)
                }
            },
            resolve: (root, args) => {
                const newAccount = new Account({
                    name: args.name
                });

                newAccount.id = newAccount._id;

                return new Promise((resolve, reject) => {
                    newAccount.save(err => {
                        if (err) reject(err);
                        else resolve(newAccount);
                    });
                });
            }
        }
    });

To get the working example: Clone the repo. In this repo, the app uses v0.13.2 and you are using v14.0.2 installed via npm i graphql. Downgrade graphql to v0.13.2.
