setDefaultsOnInsert not working with upsert

Question

I am using typegoose to create a schema, where I am defining the default field for a property. This means that if I don't set a value for that field in the setQuery, it should use that default value in the schema while inserting.

This does not work with updateOne method where I set options as {upsert: true, setDefaultsOnInsert: true}

While, if I use create, the defaults are set correctly.

Mongoose: 5.7.14 MongoDB: 3.2.20 Node: 8 Typescript: 3.8.3 Typegoose: 5.9.1

Answer 1

The reason why it wasn't working was because I was explicitly mentioning the field value as undefined .

Eg.

const updatePayload = {
id: "123",
dob: someObject.dateOfBirth
}

someObject.dateOfBirth was resulting to undefined. The defaults would have worked if I didn't have the dob key in the update payload.
