Mongoose find method is not working

async findByCategoryCode(category: string, page: number, size: number) {
    console.log(category);
    const test = await this.model.find({categoryCode: "C-1"}).explain().exec();
    console.log(test);
    const test2 = await this.model.aggregate([
        {
            $match: {
                categoryCode: "C-2"
            }
        }
    ]).exec();
    console.log(test2);
    return this.model.find({'$categoryCode': "C-1"}).skip((page - 1) * size).limit(size).exec();
}

 

const test = await this.model.find({categoryCode: "C-1"}).explain().exec();

 

const test2 = await this.model.aggregate([
    {
        $match: {
            categoryCode: "C-2"
        }
    }
]).exec();

 

explain으ㄹ 사용해서 쿼리를 봤더니 filter에 아무것도 들어있지 않았다.

데이터베이스에 code값이 없었다.
