Error on unexpected types in EdFiMetadataProcessor.cs

[jasonh-edfi]

In working with a sample data set, we've noticed that line 95 errors out on Student entity on the learningStyles field. We assume that learningStyles, as a JSON object, is an unhandled, unexpected type and needs to be handled gracefully:

System.NullReferenceException: Object reference not set to an instance of an object.
