Hi there @bfcq10282o3, thanks for reaching out.
Please see this below previous thread but the issue is likely that you do not have any credits to use toward the model.

> Thank you @ioannis . These are my screenshots, I somehow feel that they have made it paid for the new accounts. I found this in the FAQ [ChatGPT API FAQ | OpenAI Help Center](https://help.openai.com/en/articles/7039783-chatgpt-api-faq) The first question has something for free trial users but further below that it says ChatGPT API is not free.
Be sure to also set your repsonse to a text label as well.

I also want to point out, in case anyone else runs into this vague “undefined” error, you can check the console in your browser to get more specifics. In this case, when I used the Web Preview for the app in [x.thunkable.com](http://x.thunkable.com), the console showed a 429 error with my query.
A quick google search for “429 error openai” shows that this means the rate limit for my key has been exceeded. In short, I need more credits.
