Javalin, cannot get request body , except from HttpServlet directly

Question

i cannot get request body from Javalin's context object like context.formParam,context.body(),context.bodyAsClass()

i've tried like this, and i can get request body, i use HttpServletRequest directly to get request body

public void addPerson(Context ctx){
        Map<String, Object> map = new HashMap<>();

        try {
            String name = ctx.req.getParameter("person_name");
            String address = ctx.req.getParameter("person_address");
            personList.add(new Person(name,address));

            map.put("status",200);
            map.put("data","Success ");
            ctx.json(map);
        }catch (Exception ex){
            map.put("status",500);
            map.put("data","Fail");

            ctx.status(500).json(map);
        }
    }

if i change ctx.req.getParameter to ctx.formBody there will be error message in server's log

It looks like you're using an older version of Kotlin, you should upgrade to 1.3.X.
