Current behavior

Having

/* InvitationsModule
 *********************** */
import { Module } from '@nestjs/common';
import { InvitationComposerService, InvitationsService } from './services';
import { DatabaseModule } from '../database';
import { AuthModule } from '../auth';
import { MailModule } from '../mail';
import { invitationModelProvider } from './providers';

@Module({
  imports: [
    DatabaseModule.forRoot([invitationModelProvider]),
    AuthModule,
    MailModule,
  ],
  providers: [InvitationsService, InvitationComposerService],
  exports: [InvitationsService],
})
export class InvitationsModule {}

/* AuthModule
 *********************** */
import { Module } from '@nestjs/common';
import { ExternalAuthModule } from '../external-auth';

import { AuthService, ExternalAuthAdapterService } from './services';
import { AuthController } from './auth.controller';
import { AuthMiddleware } from './auth.middleware';

@Module({
  imports: [ExternalAuthModule],
  providers: [AuthService, ExternalAuthAdapterService, AuthMiddleware],
  controllers: [AuthController],
  exports: [AuthService],
})
export class AuthModule {}

where ExternalAuthModule and MailModule have no module imports,

I have this:

which leads to

Error: Nest cannot create the module instance. Often, this is because of a circular dependency between modules. Use forwardRef() to avoid it. (Read more https://docs.nestjs.com/advanced/circular-dependency.) Scope [TestModule -> InvitationsModule -> AuthModule]

Expected behavior

It should work

Minimal reproduction of the problem with instructions

Not sure. We’ve got nearly 50 modules and all are working fine.

And most of them actually use AuthModule as you might guess.

Only this one, that I’ve created recently can’t load. Any ideas on what am I doing wrong? 😃

What is the motivation / use case for changing the behavior?

Environment

Nest version: 5.0.1

Actually, i've got the same is on v4
