Couldn't find course with API id '#

Error message

Couldn't find course with API id '#{params[:course_id]}'

What it means

Guard in GradeChangeAuditApiController#for_course: api_find(Course, params[:course_id]) returned no course, so the grade-change audit query for that course is refused with ActiveRecord::RecordNotFound.

Solutions

1. Pass a valid course id (api_find also accepts SIS ids; ensure the id exists)
2. Confirm the course belongs to the current root account/shard

When it happens
