'NestJS model modelling, problem when sending HTTP request

Im trying to send a POST-request with my nestJS application. I have made the following model structure:

const WishlistSchema = new mongoose.Schema({
productID: { type: Number, required: true, unique: true },
})

export const VisitorSchema = new mongoose.Schema({
    visitorID: { type: Number, required: true, unique: true },
    wishlist: [WishlistSchema],
})

interface Wishlist {
    productID: number;
}

export interface Visitor {
    visitorID: number;
    wishlist: Types.DocumentArray<Wishlist>;
}

When I try to send a POST-request in postman like this:

{
    "visitorID": 123123,
    "productID": 3123123
}

I get the following error message "Visitor validation failed: wishlist: Cast to embedded failed for value "3123123" (type string) at path "wishlist""

Anyone that know where my mongoose schema is wrong?
