How to fix "Can't use $set" error on Mongoose - mongodb

Question

I'm using mongoose with the given schema:
const StockSchema = new mongoose.Schema(
{
"materialDefinition_id": {
"type": "ObjectId",
"ref": "MaterialDefinition",
"required": true
},
"quantity": {
"type": "Number",
"required": true
},
"committedOrder_id": {
"type": "ObjectId",
"ref": "Order"
},
"committedOrderItemIndex": {
"type": "Number"
},
"detachedOrder_id": {
"type": "ObjectId",
"ref": "Order"
},
"detachedOrderItemIndex": {
"type": "Number"
},
"deletedAt": {
"type": "Number"
},
"createdAt": {
"type": "Number"
},
"updatedAt": {
"type": "Number"
}
});
I'm getting error in the following transaction:
try {
await StockModel.update(
{
$or: [
{ committedOrder_id: purchaseOrder._id },
{ detachedOrder_id: purchaseOrder._id }
]
},
{
$set: {
committedOrder_id: null,
committedOrderItemIndex: null,
detachedOrder_id: null,
detachedOrderItemIndex: null
}
}
);
} catch (err) {
console.log("Error updating stock!");
console.log(err);
}
Error:
Error updating stock!

Any ideas on how to fix it?

From the documentation, update is executed on a document object, see document.prototype.update
You can try this instead:
await StockModel.findOneAndUpdate({
$where: { $or: [{ committedOrder_id: purchaseOrder._id }, { detachedOrder_id: purchaseOrder._id }] },
$set: {
committedOrder_id: null,
committedOrderItemIndex: null,
detachedOrder_id: null,
detachedOrderItemIndex: null
}
});
