Syntax Error with express-graphql

[sumit298]

Here I am trying to creating Graphql Schema
Code=>

`const express = require('express');

const graphqlHttp = require("express-graphql")
const { buildSchema } = require('graphql');

const app = express();

app.use(express.json());

app.use(
'/graphql',
graphqlHttp({
schema: buildSchema(`
type RootQuery {
events: [String!]!
}

    type RootMutation {
        createEvent(name: String): String
    }

    schema {
        query: RootQuery
        mutation: RootMutation
    }
`),
rootValue: {
  events: () => {
    return ['Cooking', 'Sailing', 'All-Night Coding'];
  },
  createEvent: (args) => {
    const eventName = args.name;
    return eventName;
  }
},
graphiql: true

})
);

app.listen(3000, ()=>console.log("Server up and running at Port 3000"));`

but I am getting error of

  pretty = optionsData.pretty ?? false;
                                 ^

I installed express-graphql of version 0.1.0.

Now what should I do??
