NodeJS example not working with Typescript

[schuettc]

Attempting to create a NodeJS app using SpotifyApi.withClientCredentials. When creating with JavaScript, the example here works just fine.

However, when attempting using Typescript, it fails.

import { SpotifyApi } from '@spotify/web-api-ts-sdk';

console.log('Searching Spotify for The Beatles...');

const SPOTIFY_CLIENT_SECRET = process.env.SPOTIFY_CLIENT_ID;
const SPOTIFY_CLIENT_ID = process.env.SPOTIFY_CLIENT_SECRET;

if (!SPOTIFY_CLIENT_ID || !SPOTIFY_CLIENT_SECRET) {
  throw new Error('Missing Spotify credentials');
}

const spotifyApi = SpotifyApi.withClientCredentials(
  SPOTIFY_CLIENT_ID,
  SPOTIFY_CLIENT_SECRET,
);

export const handler = async () => {
  const items = await spotifyApi.search('The Beatles', ['artist']);

  console.table(
    items.artists.items.map((item) => ({
      name: item.name,
      followers: item.followers.total,
      popularity: item.popularity,
    })),
  );

  return {
    statusCode: 200,
  };
};

handler();

{
  "name": "example_node",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "build": "tsc",

  }
}

Using the same credentials, it fails with this error:
