Error encountered while generating CCDA release

[brynrhodes]

We get an error when attempting to $release the CCDA package:

{
    "resourceType": "OperationOutcome",
    "issue": [
        {
            "severity": "error",
            "code": "processing",
            "diagnostics": "HAPI-0389: Failed to call access method: org.springframework.dao.InvalidDataAccessApiUsageException: HAPI-1764: theKey must not be null or empty"
        }
    ]
}

Attempting to $release https://github.com/cqframework/vsp-ig/blob/master/input/resources/library/Library-ccda-vsp-3-0-0-draft.json

The issue seems to be that HAPI can’t persist the v3-RoleClass CodeSystem.
It throw on this call to setKey because the value being passed in is null.
I believe the missing value corresponds to the property for the “EXLOC” code - the definition is here.
