# not found

Error message

#{e.model} not found

What it means

SetRubricSelfAssessment rescues ActiveRecord::RecordNotFound and re-raises it as GraphQL::ExecutionError "#{e.model} not found" (app/graphql/mutations/set_rubric_self_assessment.rb:65). The lookup of the assignment or rubric_association by the provided (relay or legacy) ID failed, so the resource does not exist or is invisible to this user.

Solutions

1. Re-fetch the assignment/rubric association IDs from the GraphQL API before mutating.
2. Verify the ID belongs to the same Canvas environment/shard and course.
3. Ensure the assignment actually has an active rubric association (assignment.active_rubric_association?).
4. Handle the error client-side and prompt the user to reload the assignment settings.

Example fix

// before
mutate({ variables: { id: staleAssignmentId, rubricAssociationId: cachedId } })
// after
const fresh = await client.query({ query: GET_ASSIGNMENT, variables: { id } })
mutate({ variables: { id: fresh.data.assignment.id, rubricAssociationId: fresh.data.assignment.activeRubricAssociation.id } })

const fresh = await client.query({ query: GET_ASSIGNMENT, variables: { id } }); if (!fresh.data.assignment) throw new SkipMutation('assignment not found')

try { await mutate(...) } catch (e) { if (/not found$/i.test(e.message)) { invalidateCache(); promptReload(); } else throw e; }

When it happens

Trigger: Calling the mutation with an assignment ID that has no Assignment row; a rubric association ID that no longer exists (association deleted or inactive); IDs from a different shard/course or a typo'd/legacy ID that the relay-id prepare function resolves to nothing.

Common situations: Stale UI referencing a deleted rubric association; copying IDs between Canvas environments (beta/production); passing a global ID from another root account; active_rubric_association was removed after the page loaded.
