Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

I’m currently on the free plan and using Cursor with an API key.
I’m using the o4-mini model, but I often see the error below, which makes it unusable for a while.
I’ve tried logging out and back in from the OpenAI dashboard and recreating the API key, but the error still occurs.

We encountered an issue when using your API key: Provider was unable to process your request

Request failed with status code 404: {
  "error": {
    "message": "Item with id 'xxxxxxxx' not found. Items are not persisted when `store` is set to false. Try again with `store` set to true, or remove this item from your input.",
    "type": "invalid_request_error",
    "param": "input",
    "code": null
  }
}

API Error:
(Request ID: 53adf9d5-9ddd-40a5-ae39-568db73935b4)

Steps to Reproduce

The issue happens after I’ve used it a few times, so I don’t know the exact steps to reproduce it.

Yes - Cursor is unusable

Hey, this looks like it may have been a temporary issue on OpenAI’s side, but it seems to have recovered as of about an hour ago.

Can you check if you are still facing this?

Thank you for your response.

I checked, and the communication worked successfully.
However, it’s unfortunate that even though there was a communication error, I was still charged on the OpenAI side…

Hey, thanks for the report. Could you try updating to version 1.5.7? We’ve made several improvements in this update.
