Ssh scp cmd in uipath

Hi,

I am trying to download files from a folder from a unix server into my local windows machine… I used the SSH Connection Activity. The bot connects and am able to perform simple commands like “help”,“ls”…

But when i perform the scp command… apparently, password is being asked again… which i don’t know how to fill at that stage of the bot… hence facing error…
Here is the error

The workflow screenshot:

Pls help!
