MongoDB Realm Sync会话在连接后自动断开连接

我试图连接到我的Mongo DB集合作为一个app user，与flexible sync。但同步连接自动断开后，几秒钟，它似乎。这是我的代码。

class Person extends Realm.Object {
  static schema = dummyCollectionSchema;
}
class PersonInfo extends Realm.Object {
  static schema = dummyCollection_infoSchema;
}

async function connect() {
  const app = new Realm.App({ id: "application", timeout: 10000 });
  const credentials = Realm.Credentials.emailPassword("usr", "pwd");
  const user = await app.logIn(credentials);

  const config = {
    schema: [Person, PersonInfo],
    sync: {
      user,
      flexible: true,
      initialSubscriptions: {
        update: (subs, realm) => {
          subs.add(realm.objects(Person), { name: "Persons" });
        },
      },
    },
  };
  return await Realm.open(config);
}

async function run() {
  const realm = await connect();

  console.log(`>>> Connected: ${realm.syncSession.isConnected()}`);
  // If I write a document to my collection here, it gets synced to Atlas

  // wait 10 seconds
  await new Promise(r => setTimeout(r, 10000));  
  console.log(`>>> Connected: ${realm.syncSession.isConnected()}`);
  // If I write a document  here, it does not appear in Atlas. It appears the next time I run the script though.
}

run().catch(err => console.error(`${err}`));

字符串
我没有得到任何错误（无论是在代码中，还是在域日志中），但是第二个console.log显示为Connected: false。如果我写入数据库，它总是写入本地域。但是在连接几秒钟后写入的任何内容都不会同步（下次运行代码时同步）。我在这里做错了什么？

TL;DR

下面是Realm.setLogLevel("trace")的输出

显然，你需要保持user对象活着才能有同步连接（或者看起来是这样）。当user被垃圾收集时，Realm断开连接。（我在文档中没有看到这一点）
以下工作

let user = null
async function connect() {
  ...
  user = await app.logIn(credentials);
