# X_IDEMPOTENCY_STATUS_UNKNOWN

## Means

an idempotency record holds a status this build cannot read

## Typical cause

`x_idempotency.status` holds a word this build has no branch for. The record was written by whatever build was deployed when the first attempt ran, which on a rolling deploy is not this one. Refused rather than cast: an unknown status fell past every branch of `withIdempotency` and answered `{ value: null, replayed: true }` — "this already ran, here is its result" — for a record nobody could read

## Fix

`psql "$DATABASE_URL" -c "select key, status from x_idempotency where status not in ('in-flight', 'settled', 'failed')"` — then drain the older processes
