Sails.js 通过id查找错误javascript

Question

我只想显示一个student.but有一个错误告诉我那不是一个函数

当前代码

detail: async function (req, res) {
    var thatEvent = await Event.findOne(req.params.eventid);
    if (!thatEvent) return res.notFound();

    var event = await Event.findOne(req.params.eventid).populate(
      "participants"
    );
    if (!event) return res.notFound();
    var participants = await event.participants;
    return res.json(participants);
  },

这是当前代码的结果

[
  {
    "createdAt": 1636793903089,
    "updatedAt": 1636793903089,
    "id": 3,
    "role": "student",
    "username": "student1"
  },
  {
    "createdAt": 1636793903089,
    "updatedAt": 1636793903089,
    "id": 4,
    "role": "student",
    "username": "student2"
  },
  {
    "createdAt": 1636793903089,
    "updatedAt": 1636793903089,
    "id": 5,
    "role": "student",
    "username": "student3"
  }
]

修改后

 detail: async function (req, res) {
    var thatEvent = await Event.findOne(req.params.eventid);
    if (!thatEvent) return res.notFound();

    var event = await Event.findOne(req.params.eventid).populate(
      "participants"
    );
    if (!event) return res.notFound();
    var participants = await event.participants.find({id:3});
    return res.json(participants);
  },

然后会显示不是函数的错误

error: Sending 500 ("Server Error") response: 
 TypeError: #<Object> is not a function
    at Array.find (<anonymous>)
    at Object.detail [as event/detail]

下面是我编辑的代码

 var participants = await event.participants.find({id:3});

我参考了这里的网站来修改我的代码。现在结果正确了。
https://www.codegrepper.com/code-examples/javascript/array.find+find+is+not+a+function

var participants = await event.participants.find(({ id }) => id === 3);

结果

{
  "createdAt": 1636793903089,
  "updatedAt": 1636793903089,
  "id": 3,
  "role": "student",
  "username": "student1"
}
