Google Cloud发布/订阅Java客户端库不使用本地模拟器

我正在尝试使用谷歌云发布/订阅模拟器来测试我的scala应用程序。声明如下：-

运行env init命令以确定和设置模拟器使用的环境变量。请注意，遵循这些说明后，代码中的Google Cloud发布/订阅客户端库将调用本地实例中运行的API，而不是生产API

但当我发布消息或创建主题时，它会在云中执行，而不是在本地模拟器上执行。我已经确认使用打印的

println（s“ENV:${sys.ENV（“PUBSUB\u EMULATOR\u HOST”）}

正确设置了环境变量

我尝试强制库使用我的本地设置，如下所示

val settings = TopicAdminSettings.defaultBuilder()
  .setChannelProvider(InstantiatingChannelProvider.newBuilder()
    .setEndpoint("localhost:8085")
      .setCredentialsProvider(TopicAdminSettings.defaultCredentialsProviderBuilder().build())
    .build())
  .build()

val topicAdminClient = TopicAdminClient.create(settings)
topicAdminClient.createTopic(topicName)

通过这种方式，我成功地向本地安装程序发送请求，但这会导致以下错误-

我启动了仿真器，如下所示-
