DSS boxcarring and request_box

I am facing a problem in DSS boxcarring.

I enabled boxcarring in DSS and wrote queries for selecting data from three tables separately and inserting them in another three tables. When I try using it and click on begin_boxcar then my three operations and then end_boxcar it works well. An operation (request_boxcar) is created automatically and contains my three operations in order. When I click on it on try it, it works and my operations was run but when I use task schedule and select request_box I encounter an error. I use it with my endpoint in my browser but it doesn't work. How can I fix that?

http://IP:Port/services/Test/request_box

This is the error I encountered:

Thanks for reporting this issue. This is because, it fails to retrieve the incoming message when it is called by a dataservice task. I have created a JIRA which you can find from here. You can track the progress from there, and it will be fixed in an upcoming release.
