When I use try-catch, the transaction doesn't work

[kshlove735]

@injectable()
export class ImageService {
  constructor(
    private imageRepository: ImageRepository,
    private labellingRepository: LabellingRepository,
  ) { }

  @Transactional()
  async testImageUpload(imageEntities, labellingEntities ) {

    try {
      let imagesCreated: Image[] = await this.imageRepository.save(imageEntities);
      await this.labellingRepository.save(labellingEntities);
      return imagesCreated;

    } catch (e) {
      console.log(e);
    }
  }
}

When I use try-catch, the transaction doesn't work, but when I don't use try-catch, it works. How can I use exception handling?

The transactional method executes rollback when an error is thrown in it. You should throw errors in your service and handle them in the controller.
