 Review comment:
   This endpoint will be called frequently whenever control values change, so if there's a problem with the validation endpoint we probably don't want to notify users every time (because that could create a large number of error messages). Failing silently would just result in showing all options. But we may want to be able to debug if there are issues, so I thought about putting this console log in. It doesn't seem like the best solution, but it works for now unless someone has another thought.
