Variable: INVITATION_FAILURE_REASONS

const INVITATION_FAILURE_REASONS: readonly ["provider_rejected", "provider_conflict", "account_linked_elsewhere", "person_erased", "other"]

Defined in: packages/contracts/src/schemas/identity.ts:438

Why an invitation failed, as a closed set of codes and never the provider's own words (they can quote the address or the name):

• provider_rejected: the provider refused the person as given, usually a name or an address it does not accept, or its mail system refused to send;
• provider_conflict: the provider already has an account with this address that the platform did not make;
• account_linked_elsewhere: the provider's account is already linked to another person here;
• person_erased: the person was erased before the mail went out, so none was sent;
• other: anything else; the operator's log has the code.

Widening this list is additive; narrowing it is a new version.
