从 Cloud Functions 请求预测的权限被拒绝

如何解决从 Cloud Functions 请求预测的权限被拒绝

我在 Google Cloud AI Platform 上部署了一个模型 (TensorFlow)，并在通过 Firebase 帐户部署 node.js 后尝试从 Cloud Function 获得预测。错误说：

Error: function terminated. Recommended action: inspect logs for termination reason. Additional troubleshooting documentation can be found at https://cloud.google.com/functions/docs/troubleshooting#logging Details: Permission denied on resource project skinskanproject-capstone.

这里是日志的详细信息：

Error: Permission denied on resource project skinskanproject-capstone. at Gaxios._request (/workspace/node_modules/gaxios/build/src/gaxios.js:127:23) at processticksAndRejections (internal/process/task_queues.js:97:5) at async Compute.requestAsync (/workspace/node_modules/google-auth-library/build/src/auth/oauth2client.js:343:18) at async /workspace/lib/index.js:26:19

这是 node.js 代码：

import * as functions from 'firebase-functions';

import { google } from 'googleapis';
const ml = google.ml('v1')

export const predictCancer = functions.https.onRequest(async (request,response) => {
    
    const instances = request.body.instances;
    const model = request.body.model;

    const { credential } = await google.auth.getApplicationDefault();
    const modelName = `projects/skinskanproject-capstone/models/${model}`;

    const preds = await ml.projects.predict({
        auth: credential,name: modelName,requestBody: { 
            instances
        }
    } as any);

    response.send(JSON.stringify(preds.data))

});

是否遗漏了任何 IAM 设置或身份验证步骤？
