Dentist.pas(56,18) Error: Incompatible type for arg no. 1: Got 
"TStringList", expected "TStream"

This is what I get when I use:

function ReadJSON (jsonfile, node:string) : string;
var
    json: tStringlist;
    J: TJSONData;
begin
   json:=TStringList.Create;
   json.loadfromfile(jsonfile);
   J:=GetJSON(json);    // Error is here.
   ReadJSON := J.FindPath(node).AsString;
end;

Does this mean my Lazarus / FPC is out of date? Or I'm using the wrong 
library or something?
