typescript nestjs Mongoose query, find() object inside an object

Question

In my products schema, the product information is kept in a separate object. In the code below, I am trying to fetch all the products with the trademark Apple, but the code does not work.

    async getProductWithStore(productInfoDto: ProductInfoDto) {

        try {

            const product = await this.productModel
                .find({productInfo: productInfoDto})
                .populate('store')
            return product;

        } catch (err) {
            return err;
        }



    }

Here is the request

productInfo.dto.ts

import { IsNotEmpty, IsOptional } from "class-validator";

export class ProductInfoDto {

    @IsNotEmpty()
    trademark: string;

    @IsOptional()
    releaseYear: string;

    @IsOptional()
    model: string;

    @IsOptional()
    size: string;

    @IsOptional()
    gender: string;

    @IsOptional()
    ram: string;

    @IsOptional()
    screenSize: string;

    @IsOptional()
    storage: string;

}

product.schema.ts

import { Document, Types } from 'mongoose';
import {Prop, Schema, SchemaFactory} from '@nestjs/mongoose';
import {Store} from '../../store/schemas/store.schema';
import { Category } from 'src/category/schemas/category.schema';
import { ProductInfoDto } from '../dto/product-info.dto';


export type ProductDocument = Product & Document;

@Schema({timestamps:true})
export class Product {

    @Prop({required: true})
    productName: string;

    @Prop({required: true})
    description: string;

    @Prop({required:true})
    stock: number;

    @Prop({required:true, type: Types.ObjectId, ref:'Category'})
    category: Category;

    @Prop({required:true, type:Object})
    productInfo: ProductInfoDto
    
    @Prop({required:true})
    image:string;

    @Prop({required:true, type: Types.ObjectId, ref:'Store'})
    store: Store;

    @Prop()
    sales: number;

    @Prop()
    rating: number;

    @Prop([String])
    comments: string[]


}

export const ProductSchema = SchemaFactory.createForClass(Product);

I tried a lot of things from manually typing the information into the code but none of them worked

I found the solution I replaced the .find code with the code below

async getProductWithStore(productInfoDto: ProductInfoDto) {

        try {

            const product = await this.productModel
                .find({'productInfo.trademark':"Apple"})
            return product;

        }catch(err){
            return err
        }



    }
