Idempotency-Key reused

HTTP 422

This key was already used for a different request: for an enrollment, another VIN or the other mode; for a referral, a body that differs from the first. Send a new key with a new request.

At launchFor a referral, sent from launch, to a v2 key or a signed credential: once intake checks enforce, or at once for one that can't read referrals. Until then a referral's reused key answers the first referral as a replay.

The problem body

Sent as application/problem+json, with the request id in request_id and the X-Request-Id header. Branch on code: the error and detail sentences can change, and some operations add members of their own.
