reports fail

Our reports are failing. Every time we try to run the Requirements Specification report it aborts and we not get a report. It appears that it is just the requirements artifact type that cause the problem, specifically the 'https://:443/rdm/publish/requirements' URL. Using Poster, If I get 'https://:443/rdm/publish/resources?resourceURI=rrc1548' then I get XML in the response but if I get 'https://:443/rdm/publish/requirements?resourceURI=rrc1548' then I get 'Response:500 Internal Server Error null' as the response. Additionally, I tested the '/resources' API versus '/processes', '/usecasediagrams', '/glossaries', '/usecases', and '/uisketches' without any problems.

Do we have a problem with our requirement artifacts or is it larger? How do we fix the problem so our reports run?

Thank you for your assistance.
