How can I get a player's tags when I call server.GetFriendsList?

I want to find out if the player has a certain player tag("blocked") but I don't know how to get the player's tags in CloudScript. My code returns 1 for element.Tags.length. This is correct because the player has 1 tag. But element.Tags is always empty, it doesn't return the player's tag.

How can I get the player's tags when I call server.GetFriendsList? I need to find out if the player has a certain tag.

var result = server.GetFriendsList( 
{ 
  "PlayFabId":friendid, 
  "ProfileConstraints":
  {"ShowTags":true
  }
});

if ((result != null) && (result.Error == null))
{ 
  result.Friends.forEach(element => {
  if (element.FriendPlayFabId == currentPlayerId)
  {
    log.info("element.Tags.length: " + element.Tags.length + " " + element.Tags);
    if ((element.Tags.length > 0) && (friendblocked == false))
    {
      element.Tags.forEach(tag => {
      log.info("current tag: " + tag);
      if (tag == "blocked")
      {
        friendblocked = true;
      }
      });
    }
  }
  });
}
else
{
  log.info("error");
  errorcode = result.Error;
}
