MongoDB Find by id of object inside array - mongodb

Question

I have the following Model-Structure
[{
"orders":
[{
"_id": "5f24839133759d4859ef5233",
"owner": {
"_id": "5f17fdb08145508a94fc1bda"
},
}]
},
...
]
I want to get all objects that have an order with a specific owner id.
I tried find({"orders.owner._id": "5f17fdb08145508a94fc1bda" }) which just returns an empty array.
Tried many other variations also without dot-notation, but nothing worked.
I'm using mongoose to query the MongoDB database.
EDIT:
These are the Mongoose Schemata used for the collection:
const orderPoolShema:mongoose.Schema = new mongoose.Schema({
orders: [{type: mongoose.Types.ObjectId, ref: 'Order' }]
},
{
timestamps: true
});
const orderShema:mongoose.Schema = new mongoose.Schema({
owner: {type: mongoose.Types.ObjectId, ref: 'User', require },
},
{
timestamps: true
});
const userShema:mongoose.Schema = new mongoose.Schema({
firstname: {type: String, required: true},
lastname: {type: String, required: true}
},
{
timestamps: true
});
And this is my Node.js code:
OrderPool.find({"orders.owner._id": mongoose.Types.ObjectId("5f17fdb08145508a94fc1bda") })
.then((orderPools:any) => {
res.send(orderPools);
}).catch((err:any) => {
res.status(500).send({
message: err.message || "Some error occurred while retrieving orderPools."
});
});
Any ideas on how to get that query to work are very appreciated.
Thanks for your help.
