Update $inc with Mongoose other behavior then MongoDB update - node.js

Question

I try to update a document with mongoose and it fails. The query I can successful execute directly in Mongo is like:
db.orders.update(
{
orderId: 1014428,
'delivery.items.id': '5585d77c714a90fe0fc2fcb4'
},
{
$inc: {
"delivery.items.$.quantity" : 1
}
}
)
When I try to run the following update command with mongoose:
this.update(
{
orderId: this.orderId ,
"delivery.items.id": product.id
},
{
$inc: {
"delivery.items.$.quantity" : 1
}
}, function (err, raw) {
if (err) {
console.log(err);
}
console.log('The raw response from Mongo was ', raw);
}
);
I see the following error:
{ [MongoError: cannot use the part (items of delivery.items.id) to traverse the element ({items: [ { quantity: 1, price: 6.9, name: "Manipulationstechniken", brand: null, id: "5585d77c714a90fe0fc2fcb4" } ]})]
name: 'MongoError',
message: 'cannot use the part (items of delivery.items.id) to traverse the element ({items: [ { quantity: 1, price: 6.9, name: "Manipulationstechniken", brand: null, id: "5585d77c714a90fe0fc2fcb4" } ]})',
index: 0,
code: 16837,
errmsg: 'cannot use the part (items of delivery.items.id) to traverse the element ({items: [ { quantity: 1, price: 6.9, name: "Manipulationstechniken", brand: null, id: "5585d77c714a90fe0fc2fcb4" } ]})' }
The raw response from Mongo was { ok: 0, n: 0, nModified: 0 }
I tried so many things. Any advice on this?
As requested the schema:
var Order = new Schema({
orderId: Number,
orderDate: String,
customerName: String,
state: Number,
delivery: {
items: {type: Array, default: []},
state: { type: Number, default: 0 }
}
});

TL;DR: use your model Order instead of an instance this when doing more advanced queries:
Orders.update(
{
orderId: this.orderId ,
"delivery.items.id": product.id
},
{
$inc: {
"delivery.items.$.quantity" : 1
}
}, function (err, raw) {
if (err) {
console.log(err);
}
console.log('The raw response from Mongo was ', raw);
}
);
Explanation:
Mapping differences between Model.update() and Document.update().
The using the model, then Model.update() will be used and
Model.update(conditions, doc, options, callback)
will be mapped to:
db.collection.update(query = conditions, update = doc, options)
When using an instance instead your calling Document.update() and
Document.update(doc, options, callback)
will be mapped to the following:
db.collection.update(query = {_id: _id}, update = doc, options)

Don't know if this helps, but in this question the O.P. had a similar issue with mongoose 3.6.15, and claimed it was solved in 3.8.22
EDIT: In the linked question, the O.P. had the following working on mongodb
db.orchards.update(
({"orchardId": ObjectId("5391c137722b051908000000")},
{"trees" : { $elemMatch: {"name":"apple"}}}),
{ $push: { "trees.$.fruits": ObjectId("54c542c9d900000000001234") }})
But this not working in mongoose:
orchards.update(
({"orchardId": ObjectId.fromString(orchard.id)},
{"trees" : {$elemMatch: {"name": "apple"}}}),
{$push: {"trees.$.fruits": ObjectId("54c542c9d900000000001234") }},function(err, data){ ...
In a comment, he said the issue was solved switching to mongoose 3.8.22
