我试图从firestore使用firebase函数gen2拉一个集合。我的代码看起来像下面

const { initializeApp } = require('firebase-admin/app');
const { getFirestore } = require('firebase-admin/firestore');
const { getDocs} = require("firebase-functions/v2/firestore");

initializeApp();
const db = getFirestore();

const cors = require('cors')({origin:true});

export const getReviews = onRequest(async(request, response) => {
    cors(request, response, async() => {
        logger.info("getReviews logging!", {structuredData: true});
   
        const reviews:any = []
        const appRef = db.collection("feedback");
        const appQuery = db.query(appRef);
        const querySnapshot = await getDocs(appQuery);
        querySnapshot.forEach((doc:any) => {
            let data:any 
            data = doc.data()
            reviews.push(data)
        });

        response.send(reviews);
      });
  
 });

字符串
在运行此失败与错误查询不是一个功能.
