OSLC workitem schema request

I have a production server and a test server running RTC 6.0.3.  The production server is configured and returns XML data when I enter the following URL into firefox:

<SERVER URL>:9443/ccm/rpt/repository/workitem?fields=workitem/projectArea[itemId=<Work Item UUID>]/*/*/*

When I enter the same pattern for a Work Item that has been defined in a project that exists on my test server no XML is returned. Instead I get the following error message:

Error 500: com/IBM/rational/dataservices/framework/impl/xml/format/XMLFormatterFactory.<init>(Lcom/IBM/rational/dataservices/framework/impl/xpath/FieldsConditionParser;Ljava/lang/String;I)V

I have been comparing all the settings for both the CCM and JTS including consumers and haven't found a difference that would account for why this is working on my production server and not on my test server.

Any Ideas?
