API connector - There was an issue setting up your call

Hello! Just made an account here, trying to integrate with OpenAI.
Learned how-to here: https://wgmi-academy.circle.so/c/bubble-no-code-saas/sections/63482/lessons/204712.

Using a template that does most of the heavy lifting for me.
This is the error I am getting. Please help.

Raw response for the API
Status code 429
“error”: {
“message”: “You exceeded your current quota, please check your plan and billing details.”,
“type”: “insufficient_quota”,
“param”: null,
“code”: null

Did you read the error message? You already have the answer of what to do! Check your billing and plan in the API you are calling!
