Mongodb – Can't find/update an object in an array

My collection looks like this: (Don’t ask me why it’s an array inside of a collection)

const postsSchema = mongoose.Schema({
    posts: {type: Array},
})

I want to find a document in it and I tried this:

Posts.aggregate([
        {
            $match:{
                'posts': { _id: new ObjectId(req.query.postId), }
            }
        }
])

And this:

Posts.find({
   posts: {
        $elemMatch: { "_id" : new ObjectId(req.query.postId) }
   }
})

And this:

Posts.findOne({
     'posts._id': new ObjectId(req.query.postId)
})

    const { postId } = req.query.postId;
const result = await Posts.findOne({ _id: postId })

    If you use async function you can put await else you can do .then method to get the result and avoid the await keyword

    to help you I can show you this code I made in typescript.

    use the await to retrieve the give and put your function in async

    the model (user job is the array

    const UserSchema = new Schema<UserInterface>({
    discordId: {required: true, type: "string"},
    username: {required: true, type: "string"},
    githubName: {required: true, type: "string"},
    userJob: [String],
    paypal: {type: "string", default: null},
    commandCount: {type: "number", default: 0},
    commandInProgress: {type: "number", default: 0},
})

    the get and update

    let job = "BigLol"
let result = await userModel.findOne({discordId: "0000022"});
result.userJob.push(job)
result.save();
