^^ ссылка на данные

Вот некоторые данные, которые я пытаюсь использовать. Я сделал свой собственный ключ Api и использую его в своих маршрутах. 

var router = require('express').Router();

const stockApi = 'YOUR_API_KEY';


router.get("/", function(req, res) {
  var request = require('request');
    request('https://www.alphavantage.co/query?function=TIME_SERIES_INTRADAY&symbol=MSFT&interval=1min&apikey='+stockApi, function (error, response, body) {
    var json = JSON.parse(body)
      if (error) {
        console.log(error)
      } else {
        console.log(json)
        res.render("home/home", {data:json});
      }
    });

});
module.exports = router;

Итак, я проанализировал свои данные и передал их в response.render как «данные».

Здесь я немного растерялся. Я пытаюсь распечатать метаданные и временные ряды в шаблон ejs. Но он выдаст ошибку, говоря, что forEach не является функцией. Я немного новичок в использовании данных Json в ejs. Вот мой шаблон, который я просто пытаюсь напечатать одним фрагментом данных. 

 <body>
    <%-include('../partials/navbar')%>
    <div class="container">
      <div class="row mt-4">
        <div class="col">
          <% data.forEach((stock) => { %>
            <p><%=stock.Meta_Data %></p>

          <%})%>
        </div>
      </div>
    </div>
  </body>

Также, когда я делаю запрос, я вижу все данные в консоли. Кажется, я просто не могу напечатать нужные объекты.

Вы можете сделать что-то подобное с для ... в
