soft delete from an array of objects using mongoose - node.js

Question

I am trying to soft delete an object from array using mongoose-delete lib
I Have a schema like that :
const mongooseDelete = require('mongoose-delete');
const number = new Schema({
allocation_date: { type: Date, required: true, default: Date.now() },
number: { type: String, required: true },
virtual_number: { type: String, required: true },
virtual_number_id: { type: Number, required: true, unique: true },
});
const schema = new Schema(
{
allocation_id: { type: String, required: true, unique: true },
numbers: { type: [number], required: true },
},
{
timestamps: true,
},
);
number.plugin(mongooseDelete, { deletedAt : true });
exemple data :
{
"_id": "5f7c14f9388ee9ebc0b28abc",
"allocation_id": "5_2_9387323_1"
"numbers": [
{
"allocation_date": "2020-10-06T06:55:41.197Z",
"_id": "5f7c14f997d996f7988fe8cf",
"number": "*********",
"virtual_number": "**********",
"virtual_number_id": *******,
},
{
"allocation_date": "2020-10-06T06:59:41.197Z",
"_id": "5f7c14f997d996f7988fe8cf",
"number": "*********",
"virtual_number": "**********",
"virtual_number_id": *******
}
],
"createdAt": "2020-10-06T06:55:53.367Z",
"updatedAt": "2020-10-06T06:55:53.367Z",
}
When I tried to use the delete method as follow :
const deleteNumber = await VirtualNumberAllocation.findOne(
{
'numbers.virtual_number': virtualNumber.virtualNumber,
allocation_id: virtualNumber.allocationID,
});
const activeVirtualNumber = deleteNumber.numbers.filter(
(number) => number.virtual_number==virtualNumber.virtualNumber,
);
await activeVirtualNumber[0].delete();
I'm getting this error in console:
mongoose: calling `save()` on a subdoc does **not** save the document to MongoDB, it only runs save middleware. Use `subdoc.save({ suppressWarning: true })` to hide this warning if you're sure this behavior is right for your app.
Does anyone have experience with soft deleting from an array using the library?
