Error code 453 while trying to create a Twitter bot with NodeJS and twitter-api-v2

Question

I am trying to create a very simple bot using twitter-api-v2, NodeJS and Twitter's free tier for developers. I have tried following a tutorial by Dom the dev but I keep running into the same bug, no matter what I try.

The error message

You currently have access to a subset of Twitter API v2 endpoints and limited v1.1 endpoints (e.g. media post, oauth) only. If you need access to this endpoint, you may need a different access level. You can learn more here: https://developer.twitter.com/en/portal/product

What I have tried so far

• Making sure my settings are correct on https://developer.twitter.com using two different accounts, including one that should be working because it has worked in the past (more precisely in October) It was used by somebody else than myself.
• Making sure my code doesn't contain any typo.
• Searching on the Web. Incidentally, the issue I'm talking about seems common, but the solution is not so clear.

My project has three files

twitterClient.js

const { TwitterApi } = require("twitter-api-v2");

const client = new TwitterApi({
    appKey: "",
    appSecret: "",
    accessToken: "",
    accessSecret: ""
});

const rwClient = client.readWrite;

module.exports = rwClient;

index.js

const rwClient = require("./twitterClient.js");

const tweet = async () => {
    try {
        await rwClient.v1.tweet("Good morning!");
    } catch (e) {
        console.error(e);
    }
}

tweet();

package.json

"dependencies": {
  "twitter-api-v2": "^1.15.2"
}

Answer 1

Here is the answer to my own question:

This line:

await rwClient.v1.tweet("Good morning!");

Has to be changed for this:

await rwClient.v2.tweet("Good morning!");

And voilà!
