Rubric Association not found

Error message

Rubric Association not found

What it means

If the assignment exists but has no active rubric association (assignment.active_rubric_association? is false), resolve raises "Rubric Association not found". The mutation needs a live rubric_assessments association to create a self-assessment against.

Solutions

1. Add/re-add a rubric to the assignment in the UI so an active rubric_association exists
2. Verify with assignment.active_rubric_association? before calling the mutation
3. If the rubric was deleted, restore it or choose an assignment that still has one

Example fix

// before
setRubricSelfAssessment(assignmentId: 5, ...)
// after
if assignment.active_rubric_association?
  setRubricSelfAssessment(assignmentId: 5, ...)
else
  Rails.logger.warn("assignment 5 has no active rubric association")
end

// Ruby
has_rubric = assignment.active_rubric_association?

// Ruby
begin
  mutation
rescue GraphQL::ExecutionError => e
  prompt_add_rubric if e.message == "Rubric Association not found"
end

When it happens

Trigger: Calling setRubricSelfAssessment for an assignment whose rubric was deleted or replaced, an assignment that never had a rubric added, or after a rubric import/copy that deactivated the association.

Common situations: Teacher removed the rubric after the student page loaded; course copy where rubric associations did not carry over; assignment graded without rubric in another workflow.
