What if it is a array of strings?

[AbhishekLYK]

I have an array of strings in my json like following...
{"userId":1, "rooms":["4","2","3]}

And I declared json like
-json({user, {string, "userId"},{list,"rooms",[{default,[ ]]}}})

but it is giving me error when trying to use to_json method

[Reason : {{case_clause,{error,"rooma",throw,{invalid_list_item,<<"4">>}}},[{ejson_encode,convert,5,[{file,"src/ejson_encode.erl"},{line,80}]},{ejson_encode,encode1,3,[{file,"src/ejson_encode.erl"},{line,53}]},{ejson_encode,encode,3,[{file,"src/ejson_encode.erl"},{line,32}]},{ejson,to_json,3,[{file,"src/ejson.erl"},{line,82}]}, .............

If you change ejson_enocode module's function like below

mixed_list_rule(AttrName, Value, Rules, Opts) when is_list(Value) ->
try lists:map(
fun(N) when is_number(N) ->
N;
(B) when is_boolean(B) ->
B;
(L) when is_binary(L) ->
L;
(T) when is_tuple(T) ->
Rec = element(1, T),
case encode1(T, Rules, Opts) of
{error, R} ->
throw(R);
AttrList ->
add_rec_type(Rec, AttrList)
end;
(E) ->
throw({invalid_list_item, E})
end, Value) of
List ->
{ok, {AttrName, List}}
catch
E:R ->
{error, AttrName, E, R}
end;

It works correctly. Can you update?
