I had the exact same issue but was able to solve the problem.:
raise self.handle_error_response(
openai.error.InvalidRequestError: Billing hard limit has been reached
- So I first went to - OpenAI Platform -then clicked on Setup Paid account (grey button) and added my CC. However that alone didn’t solve the issue.
- Next I went to OpenAI Platform - and created a new key. That new key worked.
Hope this helps
