I want to get data from the twitter-API-client about the most recent 3 followers.

async function get_followers() {
  const followers = await twitterClient.accountsAndUsers
    .followersList({
      count: 3,
    });
 console.log(followers);
}

// call function
get_followers();

Packages are installed properly. But it's showing an error

node:internal/process/promises:279
            triggerUncaughtException(err, true /* fromPromise */);
            ^

[UnhandledPromiseRejection: This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). The promise rejected with the reason "#<Object>".] {
  code: 'ERR_UNHANDLED_REJECTION'
}

I am using node v 8.12.1
