idempotency-in-flight

HTTP status: 409 Conflict Type URI: https://docs.evinor.ai/problems/idempotency-in-flight

Another request with the same Idempotency-Key is still being processed. Evinor runs an operation at most once per key, so a concurrent duplicate is rejected rather than executed a second time.

Common causes​

  • Two clients (or two retries) firing the same idempotent request at nearly the same time.

How to resolve​

Wait briefly and retry with the same key. Once the original request completes, retrying the same key replays its stored response instead of running the operation again. See Idempotency.
