从 mongodb 中的子文档数组中获取单个字段

Question

Below is my collection schema...

What I am trying to do is get the value of "eak" from "Website 1" and use it in my application. I am struggling to pull the value out of the multi embedded array.

_id:1234,
role:"client",
organization:"My Organization",
email:"myorg@notarealemail.com",
password:"myEncryptedPassword"
websites: 
[{
    _id:5554
    name:"Website1"
    wak:"567567567"
    wid:"5678"
    preview:"aSweetImage"
    cid:"678"
    integrations: 
    [{
        integration_data:[]
        _id:9876
        name:"Integration 1"
        img:"Integration Logo"
    },
    {
        integration_data:[]
        _id:8765
        name:"Integration 2"
        img:"Integration Logo"
        eak:"12345678"
    }]
},
{
    _id:5555
    name:"Website2"
    wak:"567567568"
    wid:"5679"
    preview:"aSweetImage"
    cid:"679"
    integrations: 
    [{
        integration_data:[]
        _id:9877
        name:"Integration 1"
        img:"Integration Logo"
    },
    {
        integration_data:[]
        _id:8766
        name:"Integration 2"
        img:"Integration Logo"
        eak:"12345679"
    }]
}] 

I have access to the "_id" for "Website 1" and am currently trying to call the value like this.

Users.find({
    eak: { "websites._id": wid, "integrations.name": "Integration 2" },
  })
    .then((eak) => {
      console.log("HERE", eak);
  })
    .catch((err) => {
      console.log(err);
  });

I have a feeling that I am simply not fully understanding the way find() works. I have read the mongodb documentation and I am clearly missing something.

the console is logging:

HERE []

There are two problems.

1. Mongo db us case sensitive. Searching for website will not result Website and Website1 is not same as website 1

2. If your resolve the above issue, you need to use positional operator to return the matching document.
