vAPI filter return no duplciate

Hi all,

I want to get the list of ran vsif from the vAPI.

For this I use the following request with following filter :

   - POST : https://serverName/vmgr/vapi/rest/sessions/list

   - filter : {"projection" : {"selection" : ["original_vsif"] } }

This request returns same file name multiple time, if it is run multiple time.

Is it possible to return each file only one time?

Thanks a lot!
