Not sure how this happens, but there's a handful of LTI linked Chimes in the database that don't have a grade mode. I can't figure out how that happens - something interfering with the form submission on the setup?
ah idea! if you import a non-canvas linked chime, we won't set a grade mode. So getSimilarChimes in LTI13Handler should filter for only Canvas-linked chimes.
