NestJS: findManyEntities not including relation table - node.js

Question

My problem is that, I have this ActivityArticle entity that is has a OneToMany relationship to ActivityArticleImage but findManyEntities is does not include the ActivityArticleImage, but when I create a custom method it works.
Here is my service that needs to work:
#Injectable()
export class ActivityArticleService extends TypeOrmCrudService<ActivityArticle> {
constructor(
#InjectRepository(ActivityArticle)
private activityArticleRepository: Repository<ActivityArticle>,
) {
super(activityArticleRepository);
}
async findManyEntities(options: FindOptions<ActivityArticle>) {
return this.activityArticleRepository.find({
relations: ['articleImage'],
where: options.where,
});
}
async getArticlesWithImage() {
return await this.activityArticleRepository.find({
relations: ['articleImage'],
});
}
}
Controller code:
#Controller({
path: 'activity-article',
version: '1',
})
export class ActivityArticleController
implements CrudController<ActivityArticle>
{
constructor(public service: ActivityArticleService) {}
get base(): CrudController<ActivityArticle> {
return this;
}
#ApiOperation({ summary: 'Get articles with image.' })
#Get('article-with-image')
#HttpCode(HttpStatus.OK)
public async getArticlesWithImage() {
return this.service.getArticlesWithImage();
}
}
Sample output for findManyEntities
Sample output for getArticlesWithImage
How can I possibly work for findManyEntities because I need its this functionality that getArticlesWithImage doesnt have
Edit:
FindOptions code:
import { EntityCondition } from './entity-condition.type';
export type FindOptions<T> = {
where: EntityCondition<T>;
};
Activity Article Entity:
#Entity()
export class ActivityArticle extends EntityHelper {
#PrimaryGeneratedColumn('uuid')
id: string;
/*other fields here*/
#OneToMany(() => ActivityArticleImage, (articleImg) => articleImg.article)
articleImage: ActivityArticleImage[];
}
Acitivity-Article-Image entity:
#Entity()
export class ActivityArticleImage extends EntityHelper {
#PrimaryGeneratedColumn('uuid')
id: string;
/*other fields here*/
#ManyToOne(() => ActivityArticle, (article) => article.articleImage)
article: ActivityArticle;
}
