# threads.container.expired

> A media container exceeded its 24-hour TTL before publish. Re-create the container.

## What it checks

Threads's two-step publish flow creates a media container, polls until it transitions to `FINISHED`, then publishes. Containers expire 24 hours after creation. If our polling sees status `EXPIRED`, this rule fires.

In practice this only fires on long-deferred publishes (the worker fell behind for >24h). Live `POST /v1/posts` calls publish within seconds.

## Failure response

```json theme={"system"}
{
  "error": {
    "code": "preflight_failed",
    "rule": "threads.container.expired",
    "platform": "threads",
    "message": "Threads media container expired before publish (24 h ttl).",
    "remediation": "Retry the publish — a new container is created on each attempt."
  }
}
```

## Remediation

Retry the publish with the same `Idempotency-Key`. The dispatcher creates a fresh container each attempt; an expired one from a previous run isn't carried forward.
