Question

我正在尝试使用@nestjs/typeorm模块并使用异步配置。在我的app.module.ts中，我有以下内容：

@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 {}

console.log打印正确的内容，但我不断收到此错误：

应该通过config服务动态地完成配置，我不明白为什么它要配置文件，为什么不能连接到数据库。

这很糟糕，我也在另一个模块中导入了TypeOrmModule.forRoot()，这引起了很多问题。
