我想问一个关于Firebase和Geofire的问题。我正在使用Firebase 9.17.1版和Geofire 6.0.0版。根据文档，我已经编写了基本代码，但收到以下错误消息：
[类型错误：t.split不是函数。（在“t.split（“/”）“中，”t.split "未定义）]
。虽然query正在工作，并且正在执行“.on“函数，但我仍然收到此错误信息。下面是我使用的代码：

class DatabaseHelper {
  private database;
  private firebaseRef: DatabaseReference;
  private app;

  constructor(){
    this.database = firebase.app().database('censored');

    this.app = initializeApp({
      apiKey: 'censored',
      appId: 'censored',
      databaseURL: 'censored',
      storageBucket: 'censored'
    });
    this.firebaseRef = ref(getDatabase(this.app));
  }

  public async addDataToGeofire(){
    const geoFire = await new GeoFire(this.firebaseRef);
    const requestId = "-NP4heZ1yLXk96HiScqH";
    const latitude = 45.502686;
    const longitude = 15.0655181;

    await geoFire.set(requestId, [latitude, longitude])
    .then(() => {
      console.log(`Coordinates successfully added to the key: ${requestId}`);
    })
    .catch((error) => {
      console.error(`An error occurred while adding the coordinate" ${error}`);
    });
  }

  public async getDataFromGeofire(){
    const geoFire = await new GeoFire(this.firebaseRef);

    await geoFire.get("-NP4heZ1yLXk96HiScqH").then(function(location) {
      if (location === null) {
        console.log("Provided key is not in GeoFire");
      }
      else {
        console.log("Provided key has a location of " + location);
      }
    }, function(error) {
      console.log("Error: " + error);
    });

    const geoQuery = geoFire.query({
      center: [47, 19],
      radius: 1000
    });

    const onReadyRegistration = geoQuery.on("ready", () => {
      console.log("GeoQuery has loaded and fired all other events for initial data");
    });

   
    // geoQuery.cancel(); <--if I call this function I don't get an error, but I don't think this is the solution.
  }
}

App.tsx:

constructor(){
  this.someMethod();    
}

async someMethod(){
  await databaseHelper.addDataToGeofire().then(async () => {await databaseHelper.getDataFromGeofire()});
}

这个错误是由geoFire.query()函数引起的，因为如果我注解掉它，我就不会收到错误消息。代码的其余部分工作正常。如果我调用geoQuery.cancel()函数，数据会被下载，并且不会抛出错误。但是，我不想取消它，因为我需要on函数继续监听。
先谢谢你
