Mongoose Type 'Promise<Document>' is not assignable to type 'Promise<Apartment>'.

[micgre0]

Hi, I use Mongoose, and I want to return from the resolver created Document type but generated resolver types making it impossible for me. Does anyone know how to get around the issue or make it works? Plugins? Thank you in advance.

Type 'Promise<Document>' is not assignable to type 'Apartment | Promise<Apartment> | Promise<ResolverTypeWrapper<Apartment>>'.
  Type 'Promise<Document>' is not assignable to type 'Promise<Apartment>'.
    Type 'Document' is missing the following properties from type 'Apartment': location, category, title, description, and 4 more.

---

type Apartment {
_id: ID!
location: String!
category: String!
title: String!
description: String!
rooms: Int!
area: Float!
price: Float
priceCurrency: Float
floor: Int!
numberOfFloors: Int!
}

You can use mappers field to map Apartment to Document inside resolvers;
https://graphql-code-generator.com/docs/plugins/typescript-resolvers

config:
   mappers:
        Apartment: Document

Apartment: import("mongoose").Document - This works but when I try

apartments: () => {
      return Apartment.find({});
    },

I got it works but I don't know is it the correct solution?
import { Apartment as ApartmentType } from "./resolvers-types";
Then

apartments: () => {
      return Apartment.find({}) as unknown as ApartmentType[];
    },

createApartmentOffer: async (_, args) => {
      ...

      const apartment = new Apartment({
        location,
        category,
        title,
        description,
        rooms,
        area,
        price,
        priceCurrency,
        floor,
        numberOfFloors,
      });

      try {
        await apartment.save();

        return apartment as unknown as ApartmentType;
      } catch (error) {
        ...
      }
    },
  },
