Encountering an issue while attempting to save the second document to MongoDB Atlas. The error message reads as follows:
Error:MongoError: E11000 duplicate key error collection: test.orders index: orderId_1 dup key: { orderId: null }Despite having no unique field specified in the document schema:
const orderSchema = new Schema({
paymentId: {
type: Number
},
paymentStatus: {
type: String
},
paymentToken: {
type: String
},
orderDetails: {
type: Object
},
}, {
timestamps: true
});
What do these error details imply? The data-saving process is carried out in the following manner:
const newOrder = new Order({
paymentId,
paymentStatus,
orderDetails,
paymentToken
});
newOrder.save()
.then(() => console.log("order saved!"))
.catch(err => console.log("error:" + err));
