Erlang / Misultin / erlsom error / process died

erlang code:

-module(index).
-compile(export_all).

-include_lib("erlsom/include/erlsom.hrl").

start(Port) ->
    misultin:start_link([{port, Port}, {loop, fun(Req) -> handle_http(Req) end}]).

stop() ->
    misultin:stop().

handle_http(Req) ->
    Var = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><request><code>1</code><var1>123456</var1><var2>qwerty</var2></request>",
    XmlErlsom = erlsom:simple_form(Var),
    Req:ok("~s", [Var]).

After I compiled the code and started the server, I opened localhost:8080/ and the shell gave me the following error:

http process <0.196.0> has died with reason: {badarg,
                                          [{erlang,list_to_binary,
                                            [[{ok,
                                               {"request",[],
                                                [{"code",[],["1"]},
                                                 {"var1",[],["123456"]},
                                                 {"var2",[],["qwerty"]}]},
                                               []}]]},

The same lib 'erlsom' for ChicagoBoss worked successfully...

After that i try with xmerl, but the result is similar.

erlsom:simple_form returns tuple of the form {ok, ParsedData}:

A = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><request><code>1</code><var1>123456</var1>`<var2>qwerty</var2></request>".

> erlsom:simple_form(A).
{ok,{"request",[],
     [{"code",[],["1"]},
      {"var1",[],["123456"]},
      {"var2",[],["qwerty"]}]},
    []}

I believe you're trying to pass this returned tuple to Req:ok(), which expects list or binary or iodata or whatever else but tuple.
