forward-ref-request-scoped-bug
A minimum reproduction repository to show off an error wth circular dependencies and implicit request scopes
forward-ref-request-scoped-bug
When using a forwardRef to resolve a circular dependency between two services, and one of the services injects a REQUEST scoped dependency, the other dependency does not see the original one as request scoped, and as such, cannot call the methods of the first dependency.
To display this, I created three dependencies
FooServiceBarServiceBazService
FooService and BarService are circularly dependent. BazService is REQUEST scoped due to injecting REQUEST, but does not use scope: Scope.REQUEST in the @Injectable() decorator. FooService injects BazService making it implicitly REQUEST scoped.
When an HTTP request is made to /, FooService calls to BarService, but AppController cannot call getBar of FooService due to the implicit request scoping, and the FooService not actually being created on the request.
