Must provide at least course_id

Error message

Must provide at least course_id

What it means

enqueue_rollup_calculation in CanvasOutcomesHelper enqueues outcome rollup calculation jobs and requires a course_id to scope the work. It raises ArgumentError immediately when course_id is nil, before checking the outcomes_rollup_propagation feature flag.

Solutions

1. Always pass course_id: when calling enqueue_rollup_calculation
2. Guard the call site: skip enqueueing when course_id is nil instead of relying on the raise
3. Trace back why the course was missing (missing param, bad association) and fix at the source
4. Ensure the caller has the course loaded from params[:course_id] before invoking

Example fix

// before
enqueue_rollup_calculation(student_id: student.id, outcome_id: outcome.id)
// after
enqueue_rollup_calculation(course_id: course.id, student_id: student.id, outcome_id: outcome.id)

raise ArgumentError, 'Must provide at least course_id' unless course_id
enqueue_rollup_calculation(course_id: course_id, ...)

begin
  enqueue_rollup_calculation(course_id: course.id)
rescue ArgumentError => e
  Rails.logger.warn("skipped rollup enqueue: #{e.message}")
end

When it happens

Trigger: Calling enqueue_rollup_calculation without course_id (or with course_id: nil), e.g. from a controller where the course param was absent, or from a job/callback that conditionally sets the course.

Common situations: A request missing the course context; refactoring changed the keyword argument name so the old value no longer binds; a batch job iterating items where some lack an associated course.
