        // We should not go in here. All exceptions should be handled in the servlet. As
        // a backup we report a server error back to the user.
        APIErrorCode internal = APIErrorCode.InternalError;
        try {
            resp.sendError(internal.getHttpStatusCode(), internal.getDescription());
