SubDocuments Validation is not working on findOneAndUpdate

This is My Model Schema:

const BalanceSchema = new Schema({
   name: { type: String, required: true },
   rate: { type: Number, required: true },
   amount: { type: Number, required: true },
});

const InvoiceSchema = new Schema({
   key: { type: String, required: true, match: /(EST|INV|BIL)-\w+/ },
   name: { type: String, required: true },
   taxes: [BalanceSchema]
});
And This How I Update my documents:

Invoice.findOneAndUpdate({
   _id: request.params.invoiceId,
  }, { status: request.body }, { new: true, runValidators: true }).exec(function (error, invoice) {
    if (error) response.apiError(error);
    if (!invoice) return response.apiNotFound();
    return response.apiResponse(invoice);
});

The problem is when I execute this function (findOnAndUpdate), the option runValidators: true doesn’t work on taxes subDocuments but only on invoice fields??!!!

Thank you for your response:

mongoose validators will only run in a findByIdAndUpdate operation with runValidators set to true on the fields you are trying to update

Can we see mongoose validators running in findOneAndUpdate in futur évolutions???

I will add it as a new feature request. I remember talking to @vkarpov15 about this and I think the plan is to make validators run by default in 5.x. However, it wont be possible to run validators for the entire object because mongoose can only see what you’re updating in a findByIdAndUpdate call. IF you want to validate an update operation based on the entire document, you’ll need to do a .save()
