google-cloud-functions - Cloud Vision 和 Cloud Functions 返回空响应

Question

我正在收听存储桶中的更改以检测图像中的人脸。并将结果记录下来。

我的功能如下

import * as functions from "firebase-functions";
import vision from "@google-cloud/vision";
import path = require('path');

const client = new vision.ImageAnnotatorClient();

export const CheckFace = functions.storage.object().onFinalize(async (image) => {
  try {
    if(image == null) return;
    const imageID = image.name;
    const contentType = image?.contentType;
    if(!contentType?.startsWith('image/')) return;
    const userID = imageID.includes(".")? path.basename(imageID).split(".")[0]:imageID;
    console.log(userID);
    
    const [result] = await client.faceDetection(`gs://${image.bucket}/${imageID}`);
    const faces = result.faceAnnotations;

    console.log(result)
    console.log(faces)
    
    if(faces == undefined || faces == null || faces.length < 0){
      console.log("noFace");
      return;
    }else if(faces.length > 1){
      console.log("more than 1");
      return;
    }else if(faces.length == 1){
      console.log("one face")
      return;
    }else{
      console.log("error")
      return;
    }
  } catch (error) {
    console.log(error);
    return;
  }
});

我得到的只是

{ 
        faceAnnotations: [],
        landmarkAnnotations: [],
        logoAnnotations: [],
        labelAnnotations: [],
        textAnnotations: [],
        safeSearchAnnotation: null,     
        imagePropertiesAnnotation: null,    
        error: null,
        cropHintsAnnotation: null,     
        fullTextAnnotation: null,     
        webDetection: null 
   }

我可能做错了什么？我已尝试添加服务帐户，但仍然遇到相同的错误。我是否需要一个服务帐户或 Firebase 管理员是否会处理它
