Hi team, I’ve been testing my React workflow in the Canvas sandbox using the default injected credentials. Since today, we’ve been constantly hitting HTTP 401 or HTTP 429 errors when calling the gemini-2.5-flash-preview-09-2025 and gemini-2.5-flash-image-preview endpoints. Can you confirm if these preview models are being phased out in the Canvas environment, or if there’s an ongoing outage/rate-limit adjustment? Thanks!
