Enrollment invitation not found

Error message

Enrollment invitation not found

What it means

Raised when no Enrollment record matches the supplied enrollment_uuid. The mutation looks up Enrollment.where(uuid: input[:enrollment_uuid]).first and raises this error when the lookup returns nil, so the invitation cannot be rejected.

Solutions

1. Verify the uuid corresponds to an existing Enrollment via Enrollment.where(uuid: ...).exists?
2. Re-send/refresh the invitation link to get the current enrollment uuid
3. Handle the already-processed case in the UI instead of re-invoking the mutation
4. Confirm you are hitting the correct Canvas environment/shard

Example fix

// before
rejectEnrollmentInvitation(courseUuid)
// after
rejectEnrollmentInvitation(enrollmentUuid) // Enrollment.find_by(uuid: enrollmentUuid)&.uuid

const enrollment = await fetchEnrollmentByUuid(uuid)
if (!enrollment) show('Invitation no longer valid')

function isEnrollment(e) { return e != null && typeof e.uuid === 'string' && e.workflowState != null }

try {
  await rejectEnrollmentInvitation({ enrollmentUuid })
} catch (e) {
  if (e.message.includes('Enrollment invitation not found')) {
    show('This invitation has expired or was already processed'); refetchState()
  } else throw e
}

When it happens

Trigger: Passing a UUID that is not an enrollment uuid (e.g. the course uuid or a user uuid); the enrollment was already accepted/rejected/deleted and purged; typo or truncated uuid; querying on the wrong shard/root account.

Common situations: Stale email links after the enrollment was re-created (regenerated uuid); user clicks 'decline' twice; uuid copied from a different environment (test vs production).
