$transaction works incorrectly in NestJS when we pass method from external service.
It doesn't roll back as expected.
Installation
$ npm install
Running the app
# development
$ npm run start:dev
Bug reproduction
# Prepare DB
$ npx prisma migrate reset --preview-feature
1) [GET] http://localhost:3000/user
Get user information, attention to user inventory item amount attribute
2) [POST] http://localhost:3000/inventory/sell
(It will throw Internal server error 500 as expected, because write2 throws error)
3) Get user information by /user. Amount not changed, so write1 rolled back successfully on write2 error.
4) Now we will use same method for write2 but from external service (user.service.ts)
Comment 52-68 and uncomment 70-86 lines in inventory.service.ts
5) [POST] http://localhost:3000/inventory/sell
(It will throw Internal server error 500 as expected, because write2 throws error)
6) Get user information by /user. Amount decremented by one, write1 didn\'t roll back on write2 error.
