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

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

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"
}

Solution

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!
