I'm using the twitter-api-v2 package and I cant save my access_token, access_token_secret and oauth_verifier. i want to save the oauth_verifier because i want to create the actual bot in another file.

Here's what I've found

• Using writeFile throws me the error in my catch statement
• Using writeFileSync keeps me stuck on the page, and does not write to the file
• Trying to tweet something works, the tweet is sent in the background, but i stay stuck on the page

client
    .login(oauth_verifier)
    .then(({ client: loggedClient, accessToken, accessSecret }) => {
      let tokens = {
        accessToken: accessToken,
        accessSecret: accessSecret,
      };
      fs.writeFile("./tokens.json", JSON.stringify(tokens));
      // loggedClient.v2.tweet("hello this is test number: 3"); << this works. i stay stuck
                                                              //on the redirect page, but the tweet is sent
    })
    .catch(() => res.status(403).send("Invalid verifier or access tokens!"));

I was able to save my access_token and access_token_secret the first time i ran this code. but I cannot anymore.

I will also add, to clear any confusion, i am not providing a service. This is a bot that i am creating to practice, and i am not providing a servce. if that is relevant.
