Error launching server on first basic tutorial

Hi, I’m following the Odyssey GraphQL Lift-off Tutorial I: Getting Started and in Lesson 5, Apollo Server, I’m having a problem. I followed the instructions and when I run the npm run start command I get a terminal error. I checked that when I run the command to be in the server folder, then, in order not to have typos I copied every line of code from the lesson, to the point where I have to run the command in the terminal. When I run npm run start I get the following error:

[nodemon] app crashed - waiting for file changes before starting…

My code:

const { ApolloServer } = require(‘apollo-server’);

const typeDefs = require(’./schema’);

const server = new ApolloServer({ typeDefs });

server.listen().then(() => {

console.log(`

🚀  Server is running!

`);

});
