this is my controller

@Controller('category')
@ApiTags('category')
@UseInterceptors(TransformResponseInterceptor)
export class CategoryController {
  constructor(
    private readonly categoryService: CategoryService,
    private readonly dataSource: DataSource,
  ) {}
  @Get()
  @ApiBearerAuth()
  @UseGuards(JwtAuthGuard, RolesNameTypeGuard)
  @RolesNameType('kasiDalpersmil')
  async readAllCategories() {
    const category = await this.dataSource.transaction(async(manager) => {
      return  await this.categoryService.getCategories({});
    })
    return {
      message: 'Success read all category',
      data: category,
    };
  }
}

this is my service

@Injectable
export class CategoryService extends TransactionFor<CategoryService> {
  constructor(
    @InjectRepository(CategoryEntity)
    private readonly categoryRepository: Repository<CategoryEntity>,
    moduleRef: ModuleRef,
  ) {
    super(moduleRef);
  }
  ...
  ...
  ...
}

[alphamikle]

Hey @tsaqifrazin1! It seems that you did not use TransactionFor<T>` method .withTransaction. U just call

return  await this.categoryService.getCategories({});

instead of

return  await this.categoryService.withTransaction(manager).getCategories({});

[tsaqifrazin1]

I'm sorry, I give you the wrong code.

@Controller('category')
@ApiTags('category')
@UseInterceptors(TransformResponseInterceptor)
export class CategoryController {
  constructor(
    private readonly categoryService: CategoryService,
    private readonly dataSource: DataSource,
  ) {}
  @Get()
  @ApiBearerAuth()
  @UseGuards(JwtAuthGuard, RolesNameTypeGuard)
  @RolesNameType('kasiDalpersmil')
  async readAllCategories() {
    const category = await this.dataSource.transaction(async(manager) => {
      return this.categoryService.withTransaction(manager).getCategories({});
    })
    return {
      message: 'Success read all category',
      data: category,
    };
  }
}

my code is like this

Hi ,

The same error was reproduced on my side, while it worked perfectly after an npm install it no longer worked I updated to the latest version but it still gives this error.

Error: Nest could not find Repository element (this provider does not exist in the current context)

[RazvanStetcu]

Same happens for me. Works fine locally but I got the same error on production environment

[mabalashov]

As a temporary solution. Downgrade packages nest/common and nest/core to version 9.2.1:

"@nestjs/common": "9.2.1",
"@nestjs/core": "9.2.1",

Works for me

Works for me too

Hey this is a possible workaround but not a solution. With newer versions of NestJS we get the above error. Is there an updated solution on this topic?

[alphamikle]

Hey @Fusix. I have very limited resources at the moment and cannot deal with the problem. If you can solve this issue with a PR, I will accept it. That way you will help yourself and others.

[cccabdalla]

i am also here reporting the same issue which i am still struggling with !

Any reliable fix ?

[cccabdalla]

9.2.1

thanks, also worked for me but would prefer better fix to be done if possible.

for me, No downgrading but upgrading from "9.0.0" to "9.2.1" !

also wondering how on earth "@nestjs/common" and "@nestjs/core" had "9.0.0" version in the first place for project which was created 2 hours ago !

[maxpeterson]

Having dug into this a little it seems that Nest is not finding the Repository dependencies anymore (dependency = this.moduleRef.get(param, { strict: false });). Using the repository token (string) seems to work so it is as if the Repository class no longer matches.

We have abandoned using nest_transact, but if someone has time I would suggest trying to create a failing NestJS example without using nest_transact.
