Accessing graph return variables in Server Side Scripts

[Khaled B]

Hello,

I'm trying the following javascript server side function. I want to access the returned user IDs :

  var gdb = orient.getGraph();

  var friends= gdb.command( "sql", "select userid from (select expand(out(\"Friend\")) from User where userid= 1)" );

  var  first_friend= friends[0]; // friends is definitely not empty

  return first_friend['userid']; // incorrect return. also tried first_friend.field("userid") and  first_friend.userid

If just returning first_friend:

[

    {

        "@type": "d",

        "@rid": "#-2:0",

        "@version": 0,

        "userid": 21

    }

]

Thank you for the help in advance.
