не получается использовать цепочки js, как правильно решить задачу?

Этот массив объектов мы будем передавать в параметр users при вызове функции из задания.

[
  {
    name: "Moore Hensley",
    email: "[email protected]",
    eyeColor: "blue",
    friends: ["Sharron Pace"],
    isActive: false,
    balance: 2811,
    gender: "male"
  },
  {
    name: "Sharlene Bush",
    email: "[email protected]",
    eyeColor: "blue",
    friends: ["Briana Decker", "Sharron Pace"],
    isActive: true,

    gender: "female"
  },

Моя попытка решить:

const users = [{
    name: "Moore Hensley",
    email: "[email protected]",
    eyeColor: "blue",
    friends: ["Sharron Pace"],
    isActive: false,
    balance: 2811,
    gender: "male"
  },
  {
    name: "Sharlene Bush",
    email: "[email protected]",
    eyeColor: "blue",
    friends: ["Briana Decker", "Sharron Pace"],
    isActive: true,
    balance: 3821,
    gender: "female"
  },
  {
    name: "Ross Vazquez",
    email: "[email protected]",
    eyeColor: "green",
    friends: ["Marilyn Mcintosh", "Padilla Garrison", "Naomi Buckner"],
    isActive: false,
    balance: 3793,
    gender: "male"
  },
  {
    name: "Elma Head",
    email: "[email protected]",
    eyeColor: "green",
    friends: ["Goldie Gentry", "Aisha Tran"],
    isActive: true,

  }
];

const getNamesSortedByFriendCount = users => {
  let newArray = users.filter(user => user.name)
    .map(user => user.friends)
    .sort((a, b) => a.friends - b.friends);

  return newArray;
};

console.log(getNamesSortedByFriendCount(users));

вывод ошибок в системе: В теле функции используется цепочка методов

Вызов функции с указанным массивом пользователей возвращает массив ['Moore Hensley', 'Sharlene Bush', 'Elma Head', 'Sheree Anthony', 'Ross Vazquez', 'Carey Barr', 'Blackburn Dotson']

Вызов функции со случайными, но валидными аргументами, возвращает правильное значение

Задание:

Дополни функцию getNamesSortedByFriendCount(users) так, чтобы она возвращала массив имён пользователей отсортированный по возрастанию количества их друзей (свойство friends).
