# SNAPSHOT_NOT_READY: The target tag's snapshot is not ready

> The snapshot the delivery API serves from this tag is not ready: still building, evicted, failed, or cancelled. `state` says which. Exporting a tag meets it too.

Sent by the management API (400). The page: https://coho-cms.com/errors/snapshot-not-ready/

## What to do

If `state` is building or evicted, wait a few seconds and retry. If it is failed or cancelled, contact Coho support.
