Индексирование вложенного массива JSON

У меня есть следующий пример JSON с массивом под "results", который содержит два объекта. Он может включать в себя сотни объектов в массиве "results" с одинаковыми ключами и разными значениями.

У меня нет доступа для изменения этого файла JSON.

У меня есть следующий код для получения и отображения нужных мне значений из каждого ключа в массиве:

const xmlhttp = new XMLHttpRequest();
xmlhttp.onload = function() {
  const myArr = JSON.parse(this.responseText);

  let text = "";
  for (let i in myArr.results) {
    text += "<div class='fed-reg-container'><h2 class='title'>" + myArr.results[i].title + "</h2><p>" + myArr.results[i].type + "</p><p>" + myArr.results[i].agencies[0].raw_name + " Document # " + myArr.results[i].document_number + "</p><p>Posted on: " + myArr.results[i].publication_date + "</p><p>" + myArr.results[i].abstract + "</p><a class='fed-reg-button' href='" + myArr.results[i].html_url + "'>Read More</a></div>";
  }
  text += "";
  document.getElementById("demo").innerHTML = text;
};
xmlhttp.open(
  "GET",
  "https://www.federalregister.gov/api/v1/documents.json?conditions%5Bagencies%5D%5B%5D=agriculture-department&conditions%5Bagencies%5D%5B%5D=federal-highway-administration&conditions%5Bagencies%5D%5B%5D=fish-and-wildlife-service&conditions%5Bagencies%5D%5B%5D=forest-service&conditions%5Bagencies%5D%5B%5D=interior-department&conditions%5Bagencies%5D%5B%5D=international-boundary-and-water-commission-united-states-and-mexico&conditions%5Bagencies%5D%5B%5D=land-management-bureau&conditions%5Bagencies%5D%5B%5D=national-highway-traffic-safety-administration&conditions%5Bagencies%5D%5B%5D=national-park-service&conditions%5Bagencies%5D%5B%5D=reclamation-bureau&conditions%5Bagencies%5D%5B%5D=environmental-protection-agency&conditions%5Bagencies%5D%5B%5D=council-on-environmental-quality&conditions%5Bagencies%5D%5B%5D=safety-and-environmental-enforcement-bureau&conditions%5Bagencies%5D%5B%5D=environment-office-energy-department&conditions%5Bcomment_date%5D%5Bgte%5D=05%2F01%2F2023&conditions%5Bcomment_date%5D%5Blte%5D=01%2F01%2F2050&conditions%5Bterm%5D=arizona&conditions%5Btype%5D%5B%5D=RULE&conditions%5Btype%5D%5B%5D=PRORULE&conditions%5Btype%5D%5B%5D=NOTICE",

Все работает отлично, кроме одного.

Как видите, мой json имеет вложенный массив под "agencies" с несколькими объектами.

Я пытаюсь использовать индексацию, чтобы получить каждое значение под raw_name каждого объекта.

Если я использую + myArr.results[i].agencies[0].raw_name, это работает для одного объекта. Может быть [0] или [1].

Когда я пытаюсь получить второе значение, например + myArr.results[i].agencies[0].raw_name + " - " + myArr.results[i].agencies[1].raw_name, весь код ломается. Я ничего не получаю взамен. Просто белая страница.

Любая идея, что я делаю неправильно?

Спасибо!
