1014: Idempotency key invalid.
Idempotency-Key is missing, repeated or malformed.
HTTP status: 400 or 422, depending on the request.
The Idempotency-Key header must be supplied exactly once as 1-255 visible ASCII bytes on every operation that requires it. A missing or malformed header is refused before the operation runs (400); one refused by the operation itself answers 422. The request was not accepted.
Troubleshooting
Section titled “Troubleshooting”- Send one Idempotency-Key header per request, generated per logical operation, and reuse it only to replay that same request.
