Rational Quality Manager (4.0.3) API - Bulk Upload not working

Hi --

I am attempting to use the bulk update capability of the RQM API.  I have used RQM 4.0.3 and RQM 4.0.4.  Here is what I am doing:

I keep receiving the following error:

400 bad request / No feed entries in the bulk upload request.

I have used Poster (Firefox) and Postman (Chrome) and received the same results.

Am I doing something wrong?  Can someone provide me with a working example of using the bulk update portion of the API?

Thanks
