firebase - firebase 功能的问题：模拟器模式和部署模式的不同输出

Question

我使用firebase函数开发了这个简单的函数，但是使用模拟器和部署函数时没有得到相同的输出

const functions = require('firebase-functions');
const tiktokScraper = require('tiktok-scraper');    


const getTrend = async (req, res) => {

    const data = []
    const posts = await tiktokScraper.trend('', { number: 5, noWaterMark: true });   

    for (let i = 0; i < posts.collector.length; i++) {       
        let message = posts.collector[i].text
        let videoUrl = posts.collector[i].videoUrl
        data.push({message, videoUrl})
    }
    
    res.send(JSON.stringify(data))

}

exports.fetchDatas = functions.https.onRequest(getTrend);

1. 使用模拟器，我确实得到了我的数据。

2. 当我部署函数时，我只得到一个空数组

你知道为什么我没有得到相同的输出吗？

干杯
