How get custom DTO type in TypeOrmCrudService?

[pavlo-dot-dev]

I have entity with unique field, i want check unique of field in EntityService.
And i have extra column "extra_field" i want use this field only when checking unique for field "name";
Problem here: "override async createOne(req: CrudRequest, dto: CreateDto) {"
Type CreateDTO not allowed, only DeepPartical allowed.
What do?

my.entity.ts

@Entity()
class MyEntity {
   @PrimaryGeneratedColumn()
   id: number;

    @Column({unique: true})
    name: string;
}

create.dto.ts

class CreateDto {
    @IsString()
    @IsNotEmpty()
    name: string;

    @IsString()
    @IsNotEmpty()
    extra_field: string;
}

my.service.ts

class MyService extendesextends TypeOrmCrudService<MyEntity> {
    constructor(
        @InjectRepository(MyEntity) repository: Repository<MyEntity>,
    ) {
       super(repository);
    }  

    override async createOne(req: CrudRequest, dto: CreateDto) {
       const checkUniqueName = await this.count({
           where: {
            name: dto.name,
          },
        });
        if( checkUniqueName )  {
            throw new Error('Field name is unique;');
        }

       const generatedName = dto.name + ':'+dto.extra_field;
 
       return super.createOne(req, {
            name: generatedName,
       });
    }    
}
