我试图让我的firebase云函数获取一些JSON并将其写入firestore。函数运行，但它似乎没有写任何东西，我似乎无法记录是否有任何实际获取？你知道为什么不给消防商店取东西和写信吗？
当我console.log(response.data.response.feedMessageResponse.messages.message)
它显示了我希望看到的JSON值，lat，lng，time等。
如果我尝试执行console.log（message.messageType），我什么也得不到。

为什么不寄给消防商店？

import axios from "axios";
import { firestore } from 'firebase-admin';

type SpotResponse = {
  response: {
    feedMessageResponse: {
      count: number,
      messages: {
        message: Array<{
          latitude: number,
          longitude: number,
          unixTime: number,
          messageType: string,
          batteryState: string,
        }>,
      },
    },
    errors: Array<{}>,
  },
}

export default async () => {
  const FirestoreInstance = firestore();
    const feedID = '0u88e3hrgRoCDA4JEqkg41U1jhO25PbvW';
    const url = `https://api.findmespot.com/spot-main-web/consumer/rest-api/2.0/public/feed/${feedID}/latest.json`;
    const response = await axios.get<SpotResponse>(url)
    const messages = response.data.response.feedMessageResponse.messages.message;
    console.log(messages);
    while (messages.length > 0) {
      const message = messages.shift();
      if (!message) throw new Error('No more items in the queue');

      const formatedMessage: any = {
        timestamp: firestore.Timestamp.fromMillis(message.unixTime * 1000),
        location: new firestore.GeoPoint(message.latitude, message.longitude),
        messageType: message.messageType,
        batteryState: message.batteryState,
      }
      Object.keys(formatedMessage).forEach(key => formatedMessage[key] === undefined && delete formatedMessage[key]);

      FirestoreInstance.collection('locationHistory').doc().create(formatedMessage)
        .then((value: firestore.WriteResult) => {
          console.log('Successfully inserted document', formatedMessage, 'at', value.writeTime);
        })
        .catch((reason: any) => {
          console.error('Could not insert document', reason);
        });
    }
  }

这是我的索引。ts

import * as functions from 'firebase-functions';
import retrievePositionData from './retrievePositionData';

const admin = require('firebase-admin');
admin.initializeApp();

export const fetchLocations = functions.pubsub
  .schedule('*/10 * * * *')
  .timeZone('America/Montreal')
  .onRun(retrievePositionData);
