X_IDEMPOTENT_REPLAY_REDACTED
Means
an idempotent replay would return a field redacted at rest
Typical cause
the stored answer for this idempotency key had a secret-named field redacted when it settled, so it cannot be replayed faithfully
Fix
x actions show '<action>' --json # the call already ran and showed its secret once — read its effect with a query; a new Idempotency-Key runs it again (a second credential)
