Error codes · Enrolling a key

Invitation already used

What it means

This invitation has already taken a key — for example, the key submission was sent again after its answer was lost. An invitation takes exactly one key, so a newly generated key pair is refused too. On the proof, this code means the proof was already accepted: its answer was lost and the same proof was sent again.

What to do

• On the proof: read the enrolment status before anything else — the key is waiting for Anis staff or already active. Do not ask for a restart.
• On the key submission: read the enrolment status first. To enrol a different key, ask Anis staff to restart the enrolment; it issues a new invitation.
• Next time, save the key submission’s answer (it carries the challenge) before anything else.

Where you can meet it

• POSTSubmit a public key/v1/enrollments/{invitationId}/keys
• POSTProve you hold the key/v1/enrollments/{invitationId}/proof

Example
