# SECRETS_TOO_LARGE

**What it means.** The app's settings exceed the 4 KB runtime limit.

**What to do.** Move large values (certificates, JSON blobs) to a file in storage and reference it by key.

- HTTP status: 400
- Retryable after applying the fix: yes

Every failure from the CLI or an MCP tool has this shape:

```json
{
  "ok": false,
  "code": "SECRETS_TOO_LARGE",
  "message": "The app's settings exceed the 4 KB runtime limit.",
  "fix": "Move large values (certificates, JSON blobs) to a file in storage and reference it by key.",
  "file": "<where to edit, when known>",
  "retryable": true,
  "docs": "https://docs.uarpie.app/errors/SECRETS_TOO_LARGE"
}
```

Apply `fix` (edit `file` when it is given), then run the same command again.
