The
sanitizeObjectfunction in prairielib usestypeof value === 'object'as a way to check ifvalueis an object, but this expression is also true fornull. This has implications in grader hosts, whenever autograders include, in the results, a key that points tonull. Instead of treating the object as null, this would trigger a parsing error on the results object. This PR fixes it by handling null values explicitly.
