Idempotency conflict
Canonical type:

Status: 409 Conflict. Browser code: idempotency_conflict.
The Idempotency-Key was already used in this namespace for a different generated-ID POST. Wispist retains each successful key and response for at least 24 hours so a lost response can be retried safely.
If this is a retry, send exactly the same method, path, and document data. If it is a new logical create, generate a new strong random key. The built-in collection.add method does this automatically.
This problem concerns POST request identity. Concurrent document revisions use Revision conflict.
