Just thought I would help out as I am stepping through this tutorial. It looks like rettiwt-api made an update that needs to be addressed here. See [github.com/Rishikant181/Rettiwt-API/issues/315](https://github.com/Rishikant181/Rettiwt-API/issues/315) [Vince Canger](https://hashnode.com/@vincanger) [Jul 6, 2023](https://hashnode.com/posts/build-your-own-personal-twitter-agent-with-langchain/649c29c04c5b78227c6b5bed/comment/64a614bad6052e06fc15db09#reply-64a68727c8506606ccf1de62) Thanks for the heads up! Those updates are probably in reference to twitter closing public access. Since we log in to twitter with Rettiwt, this shouldn’t be an issue, as we’re using the non-public methods. But if you do use the newer version let me know how it goes! [Devin Smaldore](https://hashnode.com/@speakofthedevo) [Jul 6, 2023](https://hashnode.com/posts/build-your-own-personal-twitter-agent-with-langchain/649c29c04c5b78227c6b5bed/comment/64a60b95c8506606ccf1cf5f) Hey there, [Vince Canger](https://hashnode.com/@vincanger)! First off, this is an amazing tutorial you've put together and I am looking forward to having a working version here soon! I'm running into an issue with the `export const generateNewIdeas: GenerateNewIdeas = async (_args, context) => {...}` function, specifically, it is complaining that `src/ext-src/ideas.ts(102,49): error TS2344: Type 'unknown' does not satisfy the constraint 'Payload'.` I changed the `unknown` to be of type `Payload`. Is that a sufficient enough work around? [Vince Canger](https://hashnode.com/@vincanger) [Jul 6, 2023](https://hashnode.com/posts/build-your-own-personal-twitter-agent-with-langchain/649c29c04c5b78227c6b5bed/comment/64a60b95c8506606ccf1cf5f#reply-64a686a6c8506606ccf1de5a) Ah. Try changing it to ‘never’. That should do the trick as we’re letting typescript know that this function won’t take any arguments [farah nizami](https://hashnode.com/@farahnizami887) [Jun 30, 2023](https://hashnode.com/posts/build-your-own-personal-twitter-agent-with-langchain/649c29c04c5b78227c6b5bed/comment/649f0dd25b8c3caad17893f9) Thats useful 🩷💜❤️ [Vince Canger](https://hashnode.com/@vincanger) [Jul 1, 2023](https://hashnode.com/posts/build-your-own-personal-twitter-agent-with-langchain/649c29c04c5b78227c6b5bed/comment/649f0dd25b8c3caad17893f9#reply-64a090c08db091c401034187) thanks!

It looks twitter no longer allows you to view content unless you're signed in. so you have to log in with the Rettiwt-Api once, save the tokens it returns (in your ENV VARS perhaps) and then use those to initiate the client like this. Be careful with this thought because if you dont do it correctly you could get your account suspended. Its probably best to use an alternate twitter account for this: ``` const getTokens = async () => { const tokens = await Rettiwt().account.login( process.env.TWITTER_EMAIL!, process.env.TWITTER_HANDLE!, process.env.TWITTER_PASSWORD! ); console.log('tokens: ', tokens) // save these in your env vars or somewhere safe }; //... const twitter = Rettiwt(tokens); // from above // then call twitter.tweets.getTweets() instead of twitter.users.getUserTweets const favUserTweets = await twitter.tweets.getTweets({ fromUsers: [favUser], // endDate in format YYYY-MM-DD endDate: endDate, }); ``` i'll post an update to the article and repos ASAP [Neutron](https://hashnode.com/@Neutron768) [Jun 30, 2023](https://hashnode.com/posts/build-your-own-personal-twitter-agent-with-langchain/649c29c04c5b78227c6b5bed/comment/649e861d2a0936ab01ee1e13#reply-649eb23a2a0936ab01ee24e0) [Vince Canger](https://hashnode.com/@vincanger) cool, i'll update it [Vince Canger](https://hashnode.com/@vincanger) [Jun 30, 2023](https://hashnode.com/posts/build-your-own-personal-twitter-agent-with-langchain/649c29c04c5b78227c6b5bed/comment/649e861d2a0936ab01ee1e13#reply-649eeb022a0936ab01ee2dda) tutorial has been updated!
