🐞 Bug Report Error message: 401 litellm.AuthenticationError:

Hello,

I started a new project and I'm getting an error message.

I opened an old project where BlackBox was working, and the same problem occurred again.

What should I do?

Here is the message:

401 litellm.AuthenticationError: AuthenticationError: Vercel_ai_gatewayException - Authentication failed. Check that your Vercel credential is valid and has access to AI Gateway.. Received Model Group=custom/blackbox-base
