如何从Javascript写入ROS2的日期？

Question

我可以使用NodeJS注册用户和登录。 接下来我想把数据写入ROS2，我写这段代码参考here 但是发生了错误。

Error: Object type 'Vist' not found in schema.

如何将数据写入ROS2？

const registerUser = () => new Promise((resolve, reject) => {
  Realm.Sync.User.register(URL, username, password, (err, res) => {
    if (err) {
      return reject(err);
    }
    console.log('finish register');
    resolve();
  })
});

const login = () => new Promise((resolve, reject) => {
  Realm.Sync.User.login(URL, username, password, (err, user) => {
    if (err) {
      return reject(err);
    }
    resolve(user.token);
  })
});

const registerVisit = (token) => new Promise((resolve, reject) => {
  const visitSchema = {
    name: 'Visit',
    properties: {
      id: 'int',
      oneday_id: 'string',
      arrival_date: 'string',
      departure_date: 'string',
      latitude: 'double',
      longitude: 'double',
      is_hidden: 'bool',
    }
  };

  Realm.open({ schema: [visitSchema] })
    .then(realm => {
      realm.write(() => {
        realm.create('Vist', {
          id: 1,
          oneday_id: "ABCD-EFGH-IJKL-MNOP-QRST",
          arrival_date: "2017-11-05 11:11:11",
          departure_date: "2017-11-05 22:22:22",
          latitude: 23.1234567,
          longitude: 12.34567,
          is_hidden: false,
        });
      });
      resolve();
    })
    .catch(err => reject(err));
});

login()
  .then(() => registerVisit())
  .catch(err => console.log(err));

据我看文件，没有关于如何写数据的文件。
