return crow::json::wvalue doesn't work for non "json object" types.

[The-EDev]

in the handler lambda, if you do return value_item withvalue_time being a list crow::json::wvalue object, you get nothing, it only works if you do return crow::response(value_item).

This is also true for all other non object types.

This is the code I used

CROW_ROUTE(app, "/json/thing")
([](){
        crow::json::wvalue value_item;
        std::vector<int> value_list;
        value_list.emplace_back(5);
        value_list.emplace_back(2);
        value_list.emplace_back(3);
        value_list.emplace_back(4);
        value_item = value_list;
        return value_item;
});

Found the culprit, line 415 in http_connection.h says if (res.body.empty() && res.json_value.t() == json::type::Object), should probably be changed to != json::type::Null
