Firebase调度函数在部署时出现错误

Question

我是在参考Firebase文档中的云函数来调度函数。但是在尝试部署时，它给出了以下错误。

Error: Error occurred while parsing your function triggers.

token-refresh/functions/index.js:5
export scheduledFunction = functions.pubsub.schedule('5 23 * * *').onRun((context) => {
^^^^^^

SyntaxError: Unexpected token export

我只是尝试部署文档中的确切功能，但它给出了错误。

我想部署的代码，

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

export scheduledFunction = functions.pubsub.schedule('5 23 * * *').onRun((context) => {
    console.log('This will be run at 23.05 UTC');
});

我的版本：

Firebase/ firebase-tools: 7.0.0

节点: 11.11.0

npm: 6.7.0

下面的代码应该可以工作：

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

exports.scheduledFunction = functions.pubsub.schedule('5 23 * * *').onRun((context) => {
    console.log('This will be run at 23.05 UTC');
});
