## Fix
```text
Replace the shut-down preview id with the replacement listed for it (text: gemini-3.1-pro-preview, gemini-3.6-flash, gemini-3.8-flash or gemini-3.1-flash-lite; images: gemini-nano-banana-2.1 or gemini-3-pro-image; embeddings: gemini-embedding-2; robotics: gemini-robotics-er-2-preview). Note the Gemini 2.5 GA models are access-limited to past users (AN-2026-0055), so they are not a safe fallback for new projects.
