Error when searching for a patient with medications on clinical viewer

Don't know. If you reset the Clinical Viewer, does the error stop?

Oh. Maybe some bad data. If you need this to work, you should probably contact Support.

I've run into something similar but with a different streamlet type.  The subscript error indicates that it is getting a null value which it expects to be non-null.  I would suggest looking at the medication streamlet and ensuring that all of the required fields are defined.  It might be the Medication.OrderItem.Code is null.
