I'm building an app using the Twitter API V2.0 to get user info by username and it is returning me a code 203 response.

Code:

const { TwitterApi } = require('twitter-api-v2');
const twitterClient = new TwitterApi(tokens.BEARER);
const roClient = twitterClient.readOnly;

const user = await roClient.v2.userByUsername('plhery');
console.log(user);

Response:
