使用google cloud任务调用firestore函数时的“permission_dention:缺少或不充分的权限”

Question

const functions = require("firebase-functions");

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

exports.addMessage = functions.https.onRequest(async (req, res) => {
    const original = 'dhara';
    const writeResult = await admin.firestore().collection('messages').add({original: original});
    res.json({result: `Message with ID: ${writeResult.id} added.`});
});

gcloud tasks queues create auction-autobid-queue

然后创建了谷歌云任务。

const serviceAccount = require('./my-service-account.json');

const {CloudTasksClient} = require('@google-cloud/tasks');

const client = new CloudTasksClient({
  credentials: serviceAccount
});

async function createTask() {
     const project = 'my-project';
     const queue = 'auction-autobid-queue';
     const location = 'europe-west1';
     const payload = 'Hello, World!';
     const serviceAccountEmail = "[e-mail]";
      const parent = client.queuePath(project, location, queue);
  
    const task = {
      httpRequest: {
        httpMethod: 'GET',
        url: 'https://us-central1-my-project.cloudfunctions.net/addMessage',
        oidcToken: {
          serviceAccountEmail,
        },
      },
    };
  
    const inSeconds = 60;
    if (inSeconds) {
     task.scheduleTime = {
        seconds: inSeconds + Date.now() / 1000
      };
    }
  
    console.log('Sending task:');
    console.log(task);
    const request = {parent, task};
    const [response] = await client.createTask(request);
    const name = response.name;
    console.log(`Created task ${name}`);
  }

  process.on('unhandledRejection', err => {
    console.error(err.message);
    process.exitCode = 1;
  });

  createTask();

我将此任务添加到队列中。现在，当我从Google云控制台运行这个任务时，它会抛出错误。我签入了firebase函数日志，我可以看到函数被调用，但它扔给了我

错误：7 permission_denied:缺少权限或权限不足。

我有一个服务帐户，它有云功能开发人员云功能服务代理所有者角色。

我不知道这里的问题是什么，因为分配的角色很好。

const admin = require("firebase-admin");
const serviceAccount = require("./myServiceKey.json");

const firebase = admin.initializeApp({
   credential: admin.credential.cert(serviceAccount)
});
const firestore = firebase.firestore();

exports.addMessage = functions.https.onRequest(async (req, res) => {
    const original = 'dhara';
    const writeResult = await firestore().collection('messages').add({original: original});
    res.json({result: `Message with ID: ${writeResult.id} added.`});
});
