# media_not_ready

> A message attaches media that is not ready: still uploading, failed, or from another project.

HTTP `400` · `retryable` is `false`

A message may attach only media that is uploaded, checked and ready, in the message's own project. That way an ask
is always about bytes that can no longer change.

**What to do:** wait until `GET /v2/media/{media_id}` reports `ready` (its `wait` holds until it is), then send the
message. `kabu send --file` does this for you.
