Errors
idempotency_conflict
An idempotency key was reused for a different request or while another request is still in progress.
idempotency_conflict means the submitted idempotency key cannot be accepted for this request.
Recovery guidance
Reuse an idempotency key only for the exact same mutation request. If the payload, route, or principal changes, send a new key. If the key is in progress, wait before retrying.
