// entities export class AEntity { @PrimaryGeneratedColumn("uuid")

Question

// entities export class AEntity { @PrimaryGeneratedColumn("uuid")

id: string;
@OneToMany<CEntity>(type => CEntity, entity => entity.a)
c: CEntity[];
}
export class BEntity {
@PrimaryGeneratedColumn("uuid")
id: string;
@OneToMany<CEntity>(type => CEntity, entity => entity.b)
c: CEntity[];
}
export class CEntity {
@ManyToOne<AEntity>(type => AEntity, entity => entity.c)
a: AEntity;
@ManyToOne<BEntity>(type => BEntity, entity => entity.c)
b: BEntity;
}

// method in service
findOneByRelation(aEntity: AEntity, bEntity: AEntity): Promise<CEntity | undefined>{
const findOptionsWhere: FindOptionsWhere<CEntity> = {};
findOptionsWhere.a = {id: aEntity.id};
findOptionsWhere.b = {id: bEntity.id};
return this.authRepository.findOne({
where: findOptionsWhere,
relations: this.getFindOptionsRelations<CEntity>(['a', 'b']),
});
}

// exception:
ERROR [ExceptionsHandler] Property "a, b" was not found in "CEntity". Make sure your query is correct.

Как правильно делать выборку по отношениям?
