"Failed to create API key" when trying to create a conversion API key

Hi there, I’m currently using the OpenAI ChatGPT Ads beta, and trying to set up server-side conversion tracking. However, I’ve hit a 500 error every time I try to create a key:

{
  "error": {
    "message": "The server had an error processing your request. Sorry about that! You can retry your request, or contact us through our help center at help.openai.com if you keep seeing this error. (Please include the request ID req_d7e19307cc774203ab0fe2343c7f8467 in your email.)",
    "type": "server_error",
    "param": null,
    "code": null
  }
}

Is there something I’m missing, or is this a Conversion API bug?

Thanks.

I’ve also sent this to OpenAI support; just wondering if anyone else had also encountered this.
