Seems the documentation is wrong. It needs to be updated, Can you try updating the code like below?

From

graphql(schema, "{ hello }", root).then((response) => {
  console.log(response);
});

To

graphql({
    schema: schema, 
    source: '{ hello }', 
    rootValue: root
}).then((response) => {
  console.log(response);
});
