The dollar ($) prefixed field '$oid' in 'features.0._id.$oid' is not valid for storage - mongodb

Question

I have the following Mongo collection attached below.
it is existing one not new collection created, I am trying to push new item in the features array, but I am not able to achieve that due to the following error: The dollar ($) prefixed field '$oid' in 'features.0._id.$oid' is not valid for storage.
using this script:
db.getCollection("test").update({ _id: "RYB0001" },
{
$push: {
"features": {
"_id": {
"$oid": ObjectId(),
},
"featureItems": [],
"typeId": "type3"
}
}
});
If it is a driver version issue, any workaround can I do to push the new item to the current collection?
MongoDb version: 4.0.4

The $oid notation is part of MongoDB's Extended JSON. I assume the data in your database doesn't actually have that key-value pair and it was only represented that way after using something like JSON.stringify(obj)
> db.test.find({});
{ "_id" : "RYB0001", "features" : [ { "_id" : ObjectId("5e40d46a97abdef3faa0d5d9"), "featureItems" : [ ], "typeId" : "type3" } ] }
> JSON.stringify(db.test.find({})[0]);
{"_id":"RYB0001","features":[{"_id":{"$oid":"5e40d46a97abdef3faa0d5d9"},"featureItems":[],"typeId":"type3"}]}
You'll need to generate a new ObjectId using its constructor "_id": new ObjectId(), note the new keyword there, I think #Thilo may have missed that in their comment.
db.getCollection("test").update({ _id: "RYB0001" },
{
$push: {
"features": {
"_id": new ObjectId(),
"featureItems": [],
"typeId": "type3"
}
}
});
