Something went wrong. Here's the specific error message we encountered: Operation failed after 3 attempts: 400 {"type":"error","error":{"type":"invalid_request_error","message":""claude-sonnet-4-20250514" is not supported on this API. Please use the Messages API instead."}}

@danny-avila I have Librechat deployed from a Cloud Run container. How can I follow the update steps and do a git pull and docker compose pull?
