I continue to face the same issue.
The subscription api endpoint returns 500 error. The response object is as follows
{
“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_d5e7a4af6c1551262151f63cb25b2d3f in your email.)”,
“type”: “server_error”,
“param”: null,
“code”: null
}
}
