# facebook.text.required

> Facebook posts without media require non-empty text.

## What it checks

If `media` is empty or absent, `text.trim().length > 0`. Facebook supports text-only Page posts but not empty ones.

## Failure response

```json theme={"system"}
{
  "error": {
    "code": "preflight_failed",
    "rule": "facebook.text.required",
    "platform": "facebook",
    "message": "Facebook posts without media require non-empty text."
  }
}
```

## Remediation

Provide non-whitespace `text` or attach media.
