如何在Firebase函数shell中运行Pub Sub函数

我无法在本地云函数Shell中运行pub-sub触发器。我以以下方式创建了云函数：

export const sendNotifications = functions.pubsub.schedule('0 10 * * *').timeZone('Asia/Kolkata').onRun(async (context) => {
    console.log('running sendNotificationForActivities');
    await sendMessages();
    return 0;
}

如前所述，我尝试从我的系统中运行

firebase函数：shell

，然后：

> sendNotifications({data: new Buffer('{"hello":"world"}'), attributes: {foo: 'bar'}})

或

和其他变体。以下是我收到的错误堆栈跟踪：

我想我可能缺少必需的

params

字段，但我找不到输入参数的正确方法。我正在使用

firebase-tools@7.1.1

在MacOS上。

我也有同样的错误。 错误位于cloudfunctions.js:117:28中

即使上下文不存在，他也试图访问上下文的键

我已更新到最新版本，但错误仍然存在

作为解决方法，我在cloud-functions.js的第89行添加了这段代码：context=context |{}

这解决了错误，我可以使用firebase外壳

我希望这个讨厌的黑客能有所帮助。 直到谷歌修复他们的代码或更新文档

你在GitHub上提交了问题吗？嗨！不，我没有。如果您在Firebase CLI中发现错误，请提交报告。这会有帮助的。
