Esto sucede porque debemos pasarselo como objecto

'use strict'

const { graphql, buildSchema } = require('graphql')

// definiendo el esquema
const schema = buildSchema(`
  type Query {
    hello: String
  }
`)

graphql({
    schema: schema,
    source: '{ hello }'})
.then((data) => {
  console.log(data)
})
