URGENT! Rest v6 Get agreements does not return the transient document id

Hi,

I am trying to retrive the transient document id I used when sending the agreement.
I saw in the API documentation that https://secure.na4.adobesign.com/api/rest/v6/agreements/{agreementId} has a return parameter: fileinfos (Filenfol], optional): A list of one or more files (or references to files) that will be sent out for signature.

This fileinfors contains the transient document id I need.

My problem right now is that the response does not include the fileinfos which I am expecting, is there anything I can do to get what I want?
