I have a service/provider, let’s say it’s call ServiceA1, in a module A marked as @Injectable(). In the same module i have another service/provider, let’s say it’s call ServiceA2, marked as @Injectable(). I want to inject ServiceA1 in ServiceA2 I try with:

@Injectable()
export class serviceA2 {
  constructor( @Inject('ServiceA1') private readonly serviceA1: ServiceA1){
  }
  
myFunction(integer A):  {
    const something = this.serviceA1.functionInServiceA1();
  }

}

This code throw an error: serviceA1 undefined.

My module.ts

@Module({
  imports: [],
  controllers: [],
  providers: [ServiceA1, ServiceA2]
})

I have to make another module to use serviceA2 in serviceA1?

Providers do not depend on each other, only serviceA2 depends(needs) on ServiceA1, so I think there are other solutions to using that forwardRef

@adrien2p I ended up splitting the module into two global modules. That effectively worked around the issue.
