# X_IDEMPOTENCY_REPLAYED_FAILURE

## Means

a retried `Idempotency-Key` replays a first attempt that failed after it may have committed

## Typical cause

the first attempt under this key threw and the store kept no detail of it — so nothing ran here, and what the caller is being handed is a recorded outcome, not a second execution. When the store *did* keep the first attempt's code, that code is replayed instead of this one; `meta.replayed` is `true` either way

## Fix

read the first attempt in the logs, then send a fresh `Idempotency-Key` once the cause is fixed
