Current behavior

Can't use multiple database connections, I got this error:

Nest can't resolve dependencies of the otherDb_Entity3Repository (?). Please make sure that the argument otherDbConnection at index [0] is available in the TypeOrmModule context.

Potential solutions:
- If otherDbConnection is a provider, is it part of the current TypeOrmModule?
- If otherDb Connection is exported from a separate @Module, is that module imported within TypeOrmModule?
  @Module({
    imports: [ /* the Module containing geofenceConnection */ ]
  })

Error: Nest can't resolve dependencies of the otherDb_entity3Repository (?). Please make sure that the argument otherDbConnection at index [0] is available in the TypeOrmModule context.

Expected behavior

It should work according to the documentation

Minimal reproduction of the problem with instructions

Create a module

@Module({
  imports: [
    TypeOrmModule.forFeature([Entity1, Entity2]),
    TypeOrmModule.forFeature([Entity3], 'otherDb')
  ],
  controllers: [SomeController],
  providers: [SomeService]
})
export class SomeModule {}

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

The problem I found was configuration. Someone has very helpfully updated the docs in a PR. nestjs/docs.nestjs.com#1994
