NestJs TypeORM async configuration

Question

I am trying to use the @nestjs/typeorm module and using the async configuration. In my app.module.ts I have the following:

@Module({
  controllers: [
    AppController,
  ],
  exports: [ConfigModule],
  imports: [
    ConfigModule,
    TypeOrmModule.forRootAsync({
      imports: [ConfigModule],
      inject: [ConfigService],
      useFactory: async (config: ConfigService) => {
        console.log("config.getPostgresConfig(): ", config.getPostgresConfig());
        return {
          ...config.getPostgresConfig(),
          entities,
          synchronize: true,
          type: "postgres",
        } as PostgresConnectionOptions;
      },
    }),
  ],
  providers: [AppService],
})
export class AppModule {}

The console.log prints the correct stuff, but I constantly get this error:

The config should be done all dynamically through the config service, I don't understand why it is asking for a config file, and why it can't connect to the database.

这是我的坏，我也在另一个模块中导入TypeOrmModule.forRoot() ，这导致了很多问题。
