Obisidan Copilot: Insufficient Quota Error on Paid Account with Available Balance

I am trying to use to copilot plugin from Obsidian. I generated an API keychain pasted in the system settings, and it gives me that error. I am a monthly paying customer. Please help.

I assume it’s asking for an API key from platform.openai.com?
